Everyone knows the hassle of putting earplugs in your pocket, and as they come out, it turns out they went to a club, got drunk, danced, stumbled back into your pocket and woke up with a hangover, just as you need them.
With this device, you can wind your earplugs onto the stalks, put them in their pocket/bag/man-purse, and they will come out exactly as you put them in, without tangling up into a bundle of disappointment.
When closing it, screw closed, and then it will eventually lock in place by itself.
Hopefully you will find this creation useful.
