Review on 📸 Golden State Art - Clear Bags for 5x7 Photo Mats (Pack of 100) - Preserve your Precious Memories with Perfect Fit and Crystal Clear Protection by Danielle Rogers

Really very strong, clear, excellent quality - for example the glue doesn't last too long because I made a mistake a couple of times and put the wrong card in a plastic bag and I had to replace - I managed to pull the valve off without damage - but the shell stays nice and tight when closed! They're only a hair's breadth larger than an A6 sized card and envelope combo, but I guess there really isn't a size. smaller size that fits in an A6 envelope. Highly recommended for the price. Revain have another one for the same price for a 100 pack - don't buy them. They are a lot thinner compared to how clear and durable they are.
