TOP Outdoor Pickleballs
The TOP pickleball is made of durable hard plastic and has 40 small and large holes. It is "rotationally molded," which means that a single chunk of hot plastic is placed inside a hollow rotating mold under low pressure until it has completely melted into the wall of the mold. Once cooled a bit, the mold is separated to release the hollow plastic ball. Then 40 holes are drilled into the ball. These balls are made specifically for pickleball play and meet the USA Pickleball Association's ball specifications.
