Shop Pop Tennis Balls here! Please note that POP Tennis and Platform Tennis use different balls. If you are playing in the winter time, on an elevated, heated court with a gritty surface, then you are playing Platform Tennis (although yes, players often call it “paddle” as in, “are you playing paddle this weekend?”). If this is you, please shop Platform Tennis Balls to get the proper ball. READ OUR Pop Tennis Ball Review & Buyer’s Guide.
