15 or 30 Used Tennis Balls.
Multiple Colours or all Yellow.
These tennis balls are specifically manufactured to have a lower pressure than a standard tennis ball as they are used for coaching childrens / juniors tennis, so are good for young children's ball games / smaller dogs / older dogs or puppies.
Some of them may have dirt marks / some may have initials or markings ( dots etc ) on them.
We can not guarantee any particular colours etc etc the balls sent will be a random selection of the various balls we have in stock at the time.
