Im loving these little GoTubbs. They are great to slip in a purse when you need to take a few pills, or earrings, or really any small item that you wouldnt want loose in your purse or suitcase. I think it would be a great size for a set of ear plugs for example, just lots of uses for these cute little containers. They are easy to open and seem to stay contained/closed very well. Great idea!
