Its A5 size, which for me is pretty much perfect big enough to write comfortably without feeling cramped, but not so big its a pain to carry around. It really strikes that sweet spot for versatility., the paper feels really smooth to write on. Ive tested it with a few different pens gel pens, a standard ballpoint, and even a finer-tipped marker and so far, no bleed-through or significant ghosting on the other side, which is a huge win in my book. Nothing worse than trying to write on both sides and seeing the previous pages writing trying to peek through!

Review: Initial impression: best notebook cover I've used - I have been searching and searching for just the right notebook cover for my journal and have been unable to find one to suit all of my needs until now. I have ordered several from desertcart only to find them lacking some functionality that left me overall dissatisfied. This one really seems like a keeper. I am going to go into a whole lot of detail here because everything is in Japanese and I'm going to try to answer some questions I had before I received this. I use an A5 notebook by Tumbitri Meri for my journal which I 100% recommend. I like to use fountain pens and the Tumbitri Meri stands up so much better to the ink than the Lechturm I had prior because it has 120gsm pages compared to Lechturm's 80. But I digress only to make this point: my notebook is thick. Super thick pages and 220 of them. I will be purchasing a shorter one once this one is full, but in the meantime, it's been hard to find a notebook cover or organization system that fits it. This cover has not one, not two but three separate places to hold a notebook, and two of those places give you the flexibility to add a top-bound or side-bound notebook, so if you like to use junior-sized legal pads, you can keep them alongside a journal or book. I currently have my thick notebook, the notebook that the cover came with (which btw, is a nice little notebook with a clear PVC front cover and thoughtfully designed pages), and a junior-sized legal pad to boot. And it all tucks up into a nice little (if thick) package with the exterior elastic band. My journal has a pen holder in the spine which I can thankfully still easily use while it's in this cover. I use a Pilot Decimo, but since I don't normally drop that kind of money on a pen, I can get a little anxious about it when I take it out in the wild. Tucking it into its holder on the spine of my notebook which is now safely encased on the interior of the spine of this cover eases my anxiety. I have a Sharpie pen inside the built-in pen holder as well, but this is on the outside edge of the cover and is a bit more precarious for my fanciest pen. Folded completely open, the left-hand side has a PVC pocket that can be used for a top or side bound notebook, the middle has a large pocket that can hold another notebook or supplies. Then there are three credit card slots that I have small stencils and washi tape samples in but could also be used for business cards, gift cards, etc. The right side is the fold-out leaf, which is a PVC pocket that serves to hold my notebook and could also be used for some loose papers and such. It's also capable of holding a top-bound notebook. I have wrapped the elastic on the back cover of my notebook around the fold-out for a more secure fit. There are ribbon bookmarks on the fold-out flap and between the left cover and the center portion, to help you keep your place no matter where your notebook is. They're a little superfluous for my purposes but I could see them being very helpful if my journal didn't already have 3. Both covers feature fabric pockets that could be used to hold maybe writing utensils or stencils or post-its or other supplies; I can even store my e-reader or phone here. The elastic closure on the cover is 2-3 times thicker than the one on my notebook so it seems sturdy and capable and handling the thickness of all this stuff put together. I got the navy, which in the picture looked like it had a bit more green to it, but this is a true navy color. It's handsome, though, and professional looking. And it seems sturdy and well-made. In addition to my use, I would recommend this to anyone who keeps more than one notebook (like one for work, one personal), or a journal and a planner and would like to keep them together, business professionals taking notes on meetings, artists, and people who like to take notes on their reading, lefties and others who like top-bound notebooks. Or really anyone, based on my initial impressions at least. This one is special. ## Features - [Secure Notebook Fastening] The inner pocket of this notebook cover is designed with a deep hold to securely fix the notebook's front cover in place, allowing for one-sided note-taking. You can comfortably accommodate two notebooks and fold them over during meetings to keep previous pages out of sight. - [Generous Capacity] With a wide maximum holding capacity, this cover can accommodate various types of notebooks, including ring-bound ones, thicker notebooks, and memo pads. It can hold up to 1inch in total thickness, equivalent to two notebooks with 100 pages each. - [Versatile Usage] The right pocket is designed to house ring-bound notebooks while still allowing you to utilize the unique features of these notebooks. You can fold them back for easy use and even fold them into a compact size for added convenience. The front cover pocket provides ample space to store frequently used items alongside your notebook, such as pens, sticky notes, and other small accessories. The inner pocket can also hold documents and business cards for added versatility. - [Durable Water-Resistant Material] This notebook cover is crafted from a durable, water-resistant material, ensuring long-lasting use and protecting your notes from unexpected spills or moisture. - [Complete Content Set] This package includes three bookmark strings, an A5 twin-ring edge title notebook (ス-TJ105B), an elastic closure for added security, and a convenient pen loop to ensure you have everything you need for organized note-taking on the go. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00S0GQSSE | | Best Sellers Rank | #36,172 in Office Products ( See Top 100 in Office Products ) #255 in Subject Notebooks | | Binding | Office Product | | Brand | KOKUYO | | Brand Name | KOKUYO | | Color | Black | | Cover Material | Faux Leather | | Customer Reviews | 4.7 out of 5 stars 2,625 Reviews | | Global Trade Identification Number | 04901480308579 | | Item Weight | 0.29 Kilograms | | Manufacturer | M | | Number of Items | 1 | | Number of Sections | 1 | | Pages | 100 Pages | | Paper Size | A5 | | Pattern | Solid Color | | Ruling Type | Four Line | | Sheet Size | A5 | | Special Features | Elastic closure | | Specific Uses For Product | Journal Writing, Note Taking, Office, School | | Style | Compact | | Theme | Book | ## Product Details - **Brand:** KOKUYO - **Color:** Black - **Cover Material:** Faux Leather - **Number of Items:** 1 - **Pages:** 100 Pages - **Ruling Type:** Four Line - **Sheet Size:** A5 - **Special Feature:** Elastic closure - **Style:** Compact - **Theme:** Book ## Images ![Systemic Synthetic Leather Cover Notebook, with One A5, B 6mm Ruled, 28 Lines, 50 Sheets, Twin Ring Edge Title Notebook, Black, Japan Import (NO-V685B-D) - Image 1](https://m.media-amazon.com/images/I/61qMNOvYxTL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Questions & Answers **Q: Is there any possibility of fitting an iPad mini 4 inside?** A: It will “fit” per say but there is no way to anchor it to the cover. So not advisable. **Q: Is this compatible with the koyuko smart ring binders?** A: I just tried this out and unfortunately, the plastic covers on the binder are too tall to fit in the notebook compartments here (about 0.8 cm too high)--without the covers the pages and the "binder rings" would fit. The lihit lab Aquadrops B5 "smart spiral" notebooks would just about fit. The Maruman eco spiral B5 notebooks fit too (a little snug, but the fit). I have one of these to accompany the Twin Ring Notebook that came with the cover, so I can have different subjects in different notebooks (you could just about fit three notebooks, but it's a bit tight and works much better/more smoothly with 2. I really like this notebook cover and have found in very useful. **Q: How well does this fit a large moleskine notebook?** A: A soft cover large moleskine, like the cahier, etc. should be OK. A5 is actually a bit larger than the "large" moleskine, but I think it will hold a couple quite easily. A5 size soft cover notebooks, like the Hobonichi Cousin Avecs or the Leuchtturm softcovers work GREAT in this cover. I now have two of these and love all the pockets and secure closure, as well as the very reasonable price. I sewed charms on the front to dress it up. The fabric is waterproof and very tough, so while it's not as posh as a leather cover, it's much more resistant to damage and it's also less bulky. If you need a secure, everyday carry cover for your A5, this is great. I haven't tried it with my A5 hardcovers, but they might fit if you don't load the pockets down with too much other stuff. **Q: Would a hobonichi techo cousin a5 planner fit?** A: Yes, it definitely fits. I have used it like this for multiple months now and it's perfect. There's a little extra room, but it won't move around. ## Customer Reviews ### ⭐⭐⭐⭐⭐ KOKUYO Delivers Again - A Great A5 Notebook for Work and Beyond *by T***O on March 16, 2026* Okay, so I just got my hands on this KOKUYO Systemic notebook, and honestly, Im pretty impressed right out of the box.

It is a very sturdy case. I love that it came with a notebook because one can never have too many notebooks. It does not smell like some faux leather cases do. It is very versatile and exactly what I would expect to receive from the Kokuyo brand. Overall, I would say that its value exceeds what I paid for it. It is a very well put together cover/planner system. And of course, my planner fits in it perfectly. I have it in the clear pocket since I have a clear cover on my planner. With the clear cover the planner would not fit in the back pocket, but it would if I removed the clear cover. I’m not sure if it will continue to fit well as my planner chunks up throughout the year, but if you are someone who does not add much ephemera or stickers to your planner this is a great option for a cover. ## Frequently Bought Together - KOKUYO Systemic Synthetic Leather Cover Notebook, with One A5, B 6mm Ruled, 28 Lines, 50 Sheets, Twin Ring Edge Title Notebook, Black, Japan Import (NO-V685B-D) - デザインフィル(Designphi) DESIGNPHIL 15310006 Midori Notebook, MD Notebook, Journal, A5, Dot Square A - Midori MD A5 Plain Paper Notebook from Business & School Supply --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/14341864-systemic-synthetic-leather-cover-notebook-with-one-a5-b-6mm](https://www.desertcart.pl/products/14341864-systemic-synthetic-leather-cover-notebook-with-one-a5-b-6mm) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-26*
