Got a button maker machine? Keep it stocked with this huge value pack from Mautacly! This bundle includes everything you need to make 300 custom 1.25-inch (32mm) pinback buttons. Each 'set' contains one metal cover (shell), one plastic back with a pin, one clear protective film (mylar), and one round paper insert. That's 300 of each component, all matching. Making your own buttons is a blast and super easy: just print or cut your favorite image to size (about 1.25-inch circle), place it on the metal cover, pop the clear film over it to protect it, snap it into the plastic back, and you're done! Create custom pins for your business, club, event, fundraiser, or just for fun. Perfect for crafters, teachers, and small businesses. These parts are designed to fit standard 32mm button maker presses on the market. A massive supply that will keep you creating for a long time!
