Closed the wallet is with a zipper so you can open it or fold. Cover and base are inextricably linked, but do not mind. The documents are made of felt and contrary to many opinions in forums, you can move the pieces already have on the felt, but it's not as easy as on smooth wood. That is also logical, because when setting up the wallet yes especially the underground keeps the parts in place. The felt is me personally a bit too soft. The pieces can not press as well as on hard surfaces (such as a puzzle plate).
1000 Puzzle by Ravensburger (70 x 50 cm) fit in very well, the two sorting boards can take out and put aside. They can also be used well. I find this great bag and they would all Puzzle friends who need to store their puzzle again and again, highly recommend it.
