NOS (NEW) Wilson tennis balls! "Optic Yellow Extra-Duty" USA-made USTA-approved!

Description

These are perfect NOS Wilson tennis balls  -  NEW / OLD Stock - a canister of 3, "optic yellow / extra duty".
These tennis balls are USTA-approved, and are the only tennis balls selected for use at all USTA National Championships.
(The canister seal was pulled accidentally, but these tennis balls have NEVER been USED, and they have always been stored indoors.)
If these tennis balls aren't good enough for your game, then maybe they'll be good for your dog to chase, especially if it's an older dog with poor vision (like me, lol!)
