This design is made from Delrin , an industrial strength plastic. It is used to make gears and offers outstanding durability. It has an orange head for high visibility. Place either side of the Trapper over the ball and pull slightly to allow the flipper to fall past the ball, then lift to retrieve. To release, turn the Trapper over and the ball is free. This retriever will trap the ball from either side and can scoop it from soft surfaces.
