Our natural rubber band has a specific gravity < 1 and is the best value rubber band. It has the highest yield per pound. Colored rubber bands have a little less bands in a pound, as some weight increasing fillers are used. As an example, a natural rubber band 60 mm Ø x 8 mm cut width x 1 mm wall thickness has approx. 1100 rubber bands/pound. The same rubber band in red or black has approx. 880 rubber bands/pound.
