Wish I would have thought of this SOONER! I had gotten a bad batch of silver put-together favor boxes, that popped apart, because they had not been properly glued at the factory. I tried hot glue, which left the side crooked, and once it's glued, IT'S GLUED!!!!!! However, another one recently popped open, but this time I reattached the side, using sticky photo mount squares, and they worked!!!!!! HOLDING, AND NO UNEVEN SIDE!!!! I also originally, used the squares on the underside of the bottom flaps, so the bottom didn't 'bulge'. Mary MOB

box with two photo squares
box with bottom tabs, that I put the photo squares on to hold the tabs securely
