These things are freaking adorable. Just so you know, they hold 2 TABLESPOONS MAXIMUM. Don't order them if you need something bigger than that. But if you are looking for tiny little containers, they're great. I use them for tons of things--for travel-size amounts of cosmetics and toiletries when travelling, for pills/medication, for small pieces of jewelry (especially when travelling), and for salad dressings and such in my lunch boxes. As others have noted, the lids are a bit of a challenge to get on in the beginning, but I find that as I have broken them in, they get easier and easier to close, and they provide a REALLY tight seal--no need to worry about stuff spilling out everywhere. The difficulty in closing them in the beginning is really the only reason I'm giving this 4 stars instead of 5--it seems to me like this is a fixable problem, and it is a bit of a nuisance. Overall I really love them, though.
