I wanted a set of smaller glass jars to keep out on my kitchen counters to hold my dog's daily vitamins and these are perfect. I think these would also be great for holding loose leaf tea or spices bought by the pound. 

I was a little worried about washing these with the bamboo lid but they washed up just fine (the wood didn't warp or anything). Definitely hand wash only, though! I find these are easy to open but they still have a really solid and tight seal. They also stack well on top of each other.
