Colour Changing Urinal Sticker Beer Girl - 3 Stickers

The colour-changing toilet sticker "Beer Girl" is specially designed to get your man to pee properly by aiming at the picture. The warmth of pee will cause the picture to change and a fun image will appear. 

The stickers are round and have a diameter of 35mm. 
When peeing on the discoloured pee sticker, the black ink will become transparent so that the funny picture appears as a reward.
3 stickers per pack, including clear instructions for use.
