Reusable Potty Training Stickers utilize a positive, instant reward system to assist parents and caregivers in quickly and effortlessly training a child to use the potty. They are so very easy to use for boys and girls. Just place the sticker in the bottom of the potty or above the water line in the toilet and when it gets wet (through good aim or flushing), the design appears. It disappears when it dries in a few minutes and is ready to go again! Great for children of all ages. A motivating reward! You receive three stickers per package.
