Awesome, product using these for my students for individual supply containers to hold their journal,  pencil box, dry erase board, dry erase marker, crayons, markers, and anything else they will not share with others. I purchased these with my own money so my students can be safe, so almost 275 later I hope they hold up, I say this because while putting them together several of the hinges snapped, but the function is still holding. Time will tell. Ill post pictures later.
