These handsome brooms utilize 100% recycled plastic bristles for the broom brush. The dark bristle color is typical for recycled polypropylene. The bristle ends are feathered to increase contact with the floor and to improve sweeping efficiency. The length of the bristle is designed to provide the proper amount of flex when the broom is in action. The handle is made of sustainable 15/16" diameter wood to assure a firm, ergonomic grip. Dinuba Brooms are made in California by artisans with a century old broom making tradition. You won't find a better broom anywhere!
