Thank you for viewing. This is a set of two used hard tennis balls. Dunlop Fort Used for matches and practice for 3-4 hours. I think they can be used for practice. They can also be used for purposes other than tennis. (Massage, use in washing machines, pet play, chair leg covers, etc.) The balls only will be sent by regular mail. (Price has increased from before due to the increase in regular mail rates.) No price reduction, sorry. Thank you.
