This is a set of 15 Saint James tennis balls. They were only used for 2-3 hours, 1-2 times on an omni court. The balls were only used by players in their 50s to 70s for game play, so they are in very good condition. They were only used in sunny weather. They were opened in February or later. They are being sold at a bargain price, so it's first come, first served. I am also selling many other items, so please take a look. Practice balls For practice Kids For serve practice
