HEAD CP Used Hard Tennis Balls - 15 balls. These are the same as the ones in the photos. Opened on Saturday, January 24th, and used for a 2-hour game on an omni court. They still have plenty of air. Please understand this is my assessment, and returns are not accepted. Some balls have marks from the strings. The feel is a bit softer. (My assessment) Please understand that these are used items before purchasing. You can purchase without leaving a comment. Thank you. Type: Pressure Ball Use: Hard Court
