I have used the waxy earplugs to help me sleep for a while. I love the containers, and use them for all kinds of things. I have a nice new deck of cards in one, my business cards in another, a mini sewing kit in another (in fact, the dollar trees' have mini sewing kits in them already), mini first-aid kit, craft items, and soooooooo much more! Enjoy!Add your voice to the conversation.
