This clamp has a sturdy grip with gentle, pivoting pads that adjust to the grip surface. Small teeth on the inner diameter hold muslin cloth or paper backdrops in place for photo work. Wide, flat pads hold wood pieces together while the glue dries without marring the wood. **** PACK OF 10 CLAMPS ****
