This is smaller than it looked in the picture (a good thing, as I was worried it would be too big). Perfect for keeping your flare in when they're not in your ears, both for safe keeping and to keep them clean.
These save me from losing the ear pieces, there is a slight squeak when opening though. I love that they go on my keys.
Very useful for my daughter to store her calmers in when not using them at school. Fits easily into her pocket and has helped her calmers survive the washing machine twice now!
