Since I just recently spent an entire weekend transferring all of my acrylic stamps into empty cd cases (right before this came out) and since I had to have this too I am using it for my rubons. The folders are great, all of my rubons fit, some need to be cut in half or so but it's still all good. I can use the zipper pouch for applicators or whatever. The inside cover did fall off but nothing a little bit of Fabri-Tac can't fix.
