Review: Plastic File Folders Work Well With Dry Erase Markers - Product: KTRIO Plastic File Folders, Clear Project Pockets, Transparent Plastic Sleeves, L-Type Documents Folders Jacket, Paper Sheet Protectors for Office School, Fits for Letter Size Sold by Ktrio LLC - Shipped from desertcart Purchased on Received May 3, 2023 Reviewed on June 5, 2023 I got the Plastic File Folders to use a dry erase marker (most plastics work with dry erase markers) on the printable checklists I use for Cleaning and Planning. I already use sheet protectors for my generic weekly & monthly planner pages that I keep in a notebook, but I wanted something firmer that hold up better. I wanted a good quality, non-porous plastic that was firmer than a heavy duty page protector. If the Plastic File Folders did not work for this purpose, I could still use the them as regular folders in the Paper Action Center I plan to set up. Either way they would not go to waste. I was very pleased with the feel of the folders when they got here. They are very smooth and seem to be a good quality plastic (better than the average lamination - thicker and stronger than a heavy duty page protector). When empty they look cloudy, but when you put something in it you can see it very clearly like the cloudy plastic becomes a clear plastic. I have decided to chalk it up to the same kind of magic that causes a light to come on when you flip the wall switch and not worry about why/how it works. To test its dry erase capability, I put my latest Daily Cleaning Checklist in one of the plastic file folders clip it into the clipboard and use a black dry erase marker to checked everything on the list. The marker went on well and erased without leaving any residue. So, I checked them again and waited 24 hours to erase the Morning and Evening Daily List - after a full week I erased the Weekly List - after one month (31 days) I erased the Monthly List. The result for all of them was that the black dry erase marks came off easily without leaving any residue, though I had to rub a little harder for the monthly marks. I used a dry 100% cotton dish towel to rub off the marks. Whether you want these to use as plain folders or to as dry erase pocket sleeves these work excellently. I am using them for both, they are perfect to for use in my hanging folders to separate the main category into smaller ones and being clear it is easy to find the group you are looking for. As a folder it will easily hold up to 30 sheets (you can cram in a few more if you need to) of 8.5 x 11 inch (letter size) computer paper with is plenty for most things. I ordered the 12 to try but will definitely order more next time!

## Questions & Answers

**Q: What material are these folders made of? Are they durable**
A: These folders are made of 0.2mm thick, acid-free PP plastic, much thicker than regular binder sleeves. They are wrinkle-resistant and highly durable, providing long-term protection without worrying about creases.

**Q: Are these folders compatible with A4 paper size?**
A: No, they are not suitable for A4 paper. These folders are designed for U.S. letter-size paper (8.5" x 11"), which ensures a perfect fit.

**Q: Can these folders fit into a 3-ring binder?**
A: The size is 11.5"(L) x 9"(W), which fits a standard 3-ring binder. The sleeves are not pre-punched, so you need to punch holes manually. They also fit easily into plastic folders with pockets and prongs or expandable file packages.

**Q: What are the benefits of the L-shaped opening design?**
A: The L-shape allows both top and side loading, with a thumb notch for quick access. Reinforced sealed edges at the bottom keep papers secure, and the design is also great for carrying documents alone.

**Q: Can I clean the surface of these folders if they get dirty?**
A: Yes, the folders have a smooth surface that is easy to wipe clean. They won’t leave fingerprints, so you can keep them looking clear and fresh with minimal effort.

### ⭐⭐⭐⭐⭐ Quality Product!
*by P***. on September 28, 2025*

These are good quality. I've purchased the wrong kind before and the difference in quality was pronounced. I use these sleeves to keep my project documents separate. Its great to have the division and still see clearly what's inside. Good buy.
