The puncher comes with 15 strips of material to use (but you can also make picks out of old credit cards or hotel keys), a file, and a keychain that can hold up to 10 picks.
Promising review: "I was a little skeptical at first. Sure, a pick is a simple object, but can they really be that easy to make? It turns out: yes, quick and easy. So far I have used scrap plastic from .6mm to 1.5mm, and have gotten excellent results. Just insert the stock, adjust in the eject window, and push down like a stapler. Do a little sanding and you have a custom pick." —Bill Kaneko
