Review on 25ct. Pack of Ultra PRO 9-Pocket Storage Pages with Secure Flap for 8.5'' x 11'' Albums by Gelin Battle

Purchased to attach rubber and clear postcard stamps. Each bag offers enough space for a piece of cardboard with a stamp and a piece of special plastic with a stamp attached. The valve doesn't bother, although when the stamp and picture are in the bag, the valve is so tight that it doesn't close on the hole. Since I only keep these finished sheets in a container and not in a folder, it is almost impossible for them to fall out. This probably isn't a problem if you only use trading cards or other items of the same thickness. They appear to be very solid - kept moving punches in and out etc and had no issues with tearing. Good choice!
