Product Description: This is a listing for 55 USED DUNLOP Srixon LP non-pressure tennis balls. These tennis balls offer high durability and playability. The condition of the product shows a moderate amount of use, please check the images. Srixon LP balls are non-pressure balls, so the pressure remains the same as new, and they can be used for a long time until the felt surface wears down. They can be used for both rallies and ball machine practice. They will be shipped in the DUNLOP tennis ball storage bag shown in the last image.
