Thank you for viewing. This is a set of 40 used hard tennis balls. 　Dunlop Fort: 33 balls 　SRIXON LP: 1 ball 　S t.JAMES: 1 ball 　Babolat TEAM: 5 balls These have been used for service practice, etc. They are slightly softer now. I think they can be used for service practice, etc. They can also be used for purposes other than tennis. (Massage, use in washing machines, pet play, chair leg covers, etc.) Thank you.
