Love the size - it's exactly what I was looking for there, however it takes an act of God to get the top on.  They don't fit.  I have already broken a couple of nails trying, and I don't have long nails.  That should say something. So far, I have managed to get one top on to one container.  Luckily said container was empty at the time, or it would have been pretty messy with what I had to go through in order to make it happen.  Very poorly made; I'm disappointed.
