This is a set of 15 Saint James tennis balls. They have only been used for 2-3 hours, 2-3 times on an omni court. The balls were used only by players in their 50s to 70s for game play, so they are in very good condition. They were opened between late December and early January. These are being offered at a bargain price, so it's first come, first served. I have many other items for sale, so please take a look. Practice balls For practice Kids For serve practice
