Pinback Button Set Complete set as shown in the photo. Every button is hand pressed by me and I use only the highest quality all metal parts. Each button measure one inch (1") or 25mm across.

A copper metal spring-lock pin is securely inserted in the back for attaching to your favorite anything! UV and Water Resistant. I have included a sample photo showing the button back, spring-lock pin and size comparison. **“Perfect for scrapbooks, t-shirts, hats, back packs, belts, guitar straps, book bags, purses and so much more!” Your item will be shipped safely to you within a bubble envelope.
