Grow Some Balls "Ever heard of the saying 'grow a pair', well now you don’t have to be in male formation to do so, just simply pop these balls in water and watch them grow.
These balls can grow up to six times their original size - when introduced to water, but don’t let the fun stop there, once removed from water the balls will shrink back so you can grow them over and over again! ! " A brilliant gift for the a practical joker.
Once in water, this product can grow up to 6 times bigger in 72 hours.
Once fully grown, will shrink back to original size once out of water over a few days.
