Poorly made but fits large Copic pen case
I bought these to use inside a Copic 364 pen case (the one that looks like. Duffel bag). On the upside, 8 of them fit perfectly inside the bag and they are far better than the baskets the Copic bag comes with. On the downside, they are very poorly made- 3 of them arrived with the zipper already off, and two more have lost their zippers more recently. They're fine if you don't care about zipping them- and for $5, my expectations weren't sky high- but they can't really be used as stand alone bags, unfortunately. I might end up putting a small safety pen on the zipper pull, because they really are the best option I've found for the Copic bag.
