I find it inferior to other Polymail programs. They stuck together and the plastic covering the glue kept coming loose as I took one out of the stack. They are also very thin and although listed as 10x13 they seemed to be smaller as I couldn't fit some items that I would fit in other brands of 10x13 resin mailboxes. When I measured them, if they weren't 10 inches wide - it turned out to be 0.2 inches smaller. I will not buy them again because of the poor quality and not the stated size.
