Caution; these are BIG! Two inches across doesn't seem large, but if you are using it to bead around, two inches can be fairly large, LOL! These still have a great place in beadwork, however; they would be perfect to apply a photo to and bead around, (think how cute that picture you have of the kiddo sticking their tongue out at you would be, immortalized in beadwork....lol) or you could use them as a nice sturdy base to apply beadwork to before appling it to a purse flap, backpack, etc. Drill them, etch them, glue pretty things to them......dozens of uses!! Solid Brass, but thin enough (.5mm) to be lightweight, yet strong.
