The Original Weighted Rubber Bookmark. You’ll love ’em. BookBones are always available in your choice of three bright colors; Red, Blue or Green. We occasionally cast BookBones in different colors just for fun. Search “BookBones” to see current additional colors available. Cast in urethane with weights permanently molded in each end, they’re washable, stain and chemical resistant and they’ll last a lifetime. They’re available unprinted or printed with your choice of our standard art (see photo). We invented them and we hand make and ship them from Savannah Georgia U.S.A.
