"We used these empty favor boxes for my son's 6th Birthday party. We added a little "R" (as in Robin) symbol to each box to make it fit our Teen Titans theme. The boxes are tough enough to stand up to my children assembling them and also to the Little Heroes getting into them constantly throughout the party. Whenever the party guests got a prize, candy, or just had extra craft supplies, I would tell them, "Stick it in your box." One creative little girl even embellished her box using the circle stickers from our BINGO game. I was worried at first that the bottom of the boxes may not stay in place without some sort of tape or adhesive, but I decided to trust the product as it came, and we didn't have even a single incident of breakage. The boxes are fabulous!!! I would definitely use them again for any party where the guests are going to be taking things home."
