"As a previous reviewer noted, the description is very clear that the lids do not snap on. However, they do STAY on, unless you turn the box over. I like this style very much because I don't have to keep helping my kids open the boxes, as I do with others in our house. Also, the lids have indentations that not only allow for stacking but keep the top boxes in place.
My only qualm is the cost. With shipping, the 3 boxes I bought cost $30. Yes, they're really nice, but they're just....plastic boxes. If I hadn't had a gift card I'm not sure I would have bought them. On the other hand, now that I have them I see how nice they look, & they certainly meet my needs."
