I use these for drawing rather than writing and the quality is impeccable. They are on the more expensive side but nowhere else can I get such consistently fine lines. I like that they are refillable (the isographs so much more so than the rapidographs). For good consistent flow without having to clean them, these pens need to be used regularly. Weeks without using them can lead to splotchy lines or blocked pens. Review: Reliable. ink flow joy. Refillable and sustainable. Zero waste. - This is a great pen. It draws smoothly and reliably. Takes India Ink which is waterproof and permanent. Way cheaper and sustainable to use a refillable pen than keep buying disposable pens. I bought a 250ml bottle of ink; way cheaper than the tiny ones. The steel nib will last forever. I use it most days. But if I leave it for a while, a good shake and the ink flows like a dream. I had been using cheaper brands, which were fine for a while, and then clogged and stopped working, even after extensive cleaning and faffing about. Grrr factor 10/10 after several months of use. As an artist and not a technical draughtsperson, I really rate these pens. Mine is a 0.6 nib. Can't vouch for the reliability of the finer nibs. However, it is too easy to over-tighten the grey nib holding section against the handle / barrel. Mine has a hairline crack, allowing the barrel to rotate a bit and be annoying. But it does not affect the drawing function, or ink flow, just the handling of the barrel. Still useable, but would like a better quality plastic at that point in the design. I have not been heavy handed with it. It was just a bit weak there on the thread. Having said which, it is far superior to the cheaper brands. I wasted money buying several cheapos, thinking I had simply bought a rogue pen initially. Not so. The working parts were just not as good as Rotring. Invest in the best. ## Features - High precision 0.25 mm pen with refillable ink reservoir for drawing - The hard chrome-plated thin tip produces exquisite, detailed work - The wear-resistant tip prevents dripping and blobbing - Designed so that ink level is clearly visible, so you know when it's time to replace the ink - Ideal for use on a variety of surfaces including line board, tracing paper and vellum drawing paper ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00JXIRC92 | | Age Range Description | Adult | | Best Sellers Rank | 12,101 in Stationery & Office Supplies ( See Top 100 in Stationery & Office Supplies ) 3 in Technical Pens | | Body Shape | Cylindrical | | Brand Name | rOtring | | Closure Type | Snap closure | | Colour | Black | | Country Of Origin | Germany | | Customer Reviews | 4.3 4.3 out of 5 stars (1,924) | | Drill Point | Fine | | Global Trade Identification Number | 03501179033983 | | Grip Type | Knurled | | Hardness | H | | Included Components | Ink Cartridge, Ink Converter | | Ink Base | Alcohol | | Ink Colour | Black | | Is the Product Left or Right Handed? | Right | | Item Dimensions | 15 x 10 x 3 centimetres | | Item Type Name | Ink fountain pen | | Item Weight | 10 Grams | | Line Size | 0.25mm | | Manufacturer | Newell Rubbermaid | | Material Type | Edelstahl, Karton | | Model Name | Isograph | | Model Number | 1903398 | | Pattern | Einzelstück | | Product Warranty | no Guarantee | | Recommended Uses For Product | technical drawing, architectural drawing, engineering drawing, sketching detailed designs, artistic illustration | | Special Features | Refillable | | Style | 0.25 mm | | Theme | Writing Instrument | | Water Resistance Level | Not Water Resistant | | Writing Instrument Form | Technical Pen | ## Product Details - **Age range (description):** Adult - **Brand:** rOtring - **Colour:** Black - **Ink colour:** Black - **Item dimensions L x W x H:** 15 x 10 x 3 centimetres - **Material:** Edelstahl, Karton - **Model name:** Isograph - **Point type:** Fine - **Special feature:** Refillable - **Writing instrument form:** Technical Pen ## Images ![Isograph Technical Drawing Pen | 0.25 mm | Refillable Fineliner Pen - Image 1](https://m.media-amazon.com/images/I/61blSXzM54L.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: what type of ink can you refill this with?** A: The other answer is incorrect. Isographs have a refillable container on the inside that you fill with bottled ink. It's the Rapidograph that requires cartridges, not this. **Q: are the pens metal or plastic?** A: These pens have plastic bodies. ## Customer Reviews ### ⭐⭐⭐⭐⭐ My favourites! *by I***A on 12 October 2025* These are my favourite pens!

Fine non splodgy line for crisp drawings. Prone to clogging but if you look after them they’ll last a long time.. Arrived well packaged in a nice box. ## Frequently Bought Together - Rotring Isograph Technical Pen, 0.25 mm - rOtring Isograph Technical Drawing Pen, Liquid Ink, 23 ml, Black - Rotring Isograph Technical Drawing Pen, 0.35 mm --- ## 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/49955662-isograph-technical-drawing-pen-0-25-mm-refillable-fineliner-pen](https://www.desertcart.pl/products/49955662-isograph-technical-drawing-pen-0-25-mm-refillable-fineliner-pen) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-15*
