The Ace 2 Outdoor Pickleball Ball is great value for money, especially when you consider that it is USAPA/IFP tournament approved. It is made of durable hard plastic which is seamless and has 40 holes, some large and some smaller. It is traditionally used outdoors but can also be used indoors for a slightly faster game. It plays just as well as the more expensive balls and lasts just as long. Pack size 12 balls, color yellow only.
