Fun, quiet and safe! Each set is hand made from reclaimed fabrics. All pins are weighted at the base and the ball is also. They are weighted with a small pouch, filled with rice, so they are safer if a teething puppy or baby make it through to the inside! As with all handmade, custom crafted items, each pin has slight variations but are approximately 8" tall by 3 1/2" inches wide. Each set will include 6 pins and a matching bowling ball.
