Thank you for viewing. 105 used hard tennis balls. A mix of FORT, St. JAMES, and HD. Used on an omni court. Used for 2-4 hours, about twice a week, with varying conditions. Used for 3 months after opening. I think they can still be used for practice. Please note that the ball pressure has decreased compared to new balls as they are used balls. About 2 balls have magic marker markings. Please consider only if you understand that these are used items. Thank you. The price includes shipping, so please refrain from negotiating a discount. Purpose: Hard court Type: Pressure ball
