Our Gender Reveal Golf Ball Kit comes with two pre-filled golf balls. One ball is filled with vibrant non-toxic blue colored powder and the other is filled with pink powder. When the kit arrives the balls will come with a pink or blue sticker on them, you will then pick which ball you need. When ready to reveal the gender place the golf ball on the provided golf tee and get ready to swing! We suggest to use a driver for the best results. We can ship orders out the same day if placed before 2pm CST. Share your photos and videos with us, on our social media pages.
