Mint tins are one of the most useful containers in the world. I’ve used them for mini sewing kits, mini first-aid kits, cough drops, batteries, extra SD cards for my camera, hair rubberbands, jewelry on vacations, all kinds of things. Here’s my favorite use so far, though….
It’s a cheap & easy way to keep your headphones neat & protected in your purse or backpack. No need to do any complicated wrapping, no worry about fraying the wires from wrapping too tight. Keeps dust & grit from the bottom of your bag from gunking up the earbuds, unlike many wrapping methods.
If your mp3 player is small & thin, it might even fit in there with them. My Sansa Fuze does.
So go get a tin of mints, drop them in a ziplock bag to share with friends, wipe the dust out of the tin, and you’re good to go.
