- Our gender reveal golf ball sets include 4 balls (4 blue or 4 pink). Each ball is filled to the very top with vibrant pink or blue powder to ensure the largest explosion for the reveal. The balls are marked with either a removable pink or blue dot/sticker to indicate the powder within the golf ball. - All balls are made with durable plastic to ensure that the balls will not break during shipping or even if dropped on grass or soft clay. Although durable, the balls will certainly explode when struck with the golf club. The harder you hit the ball with your driver, the bigger explosion you will get. So swing away! - We strive to have the very best quality gender reveal golf balls on the market. We aim to make your gender reveal party as special and unique as possible with our golf balls. The four balls will be in a white 4 ball sleeve golf ball box.
