These are black when in colder climates but turn neon green with a warm touch or warm weather! Now you see it, now you don't! Our temperature reactive nipple pasties will make onlookers do a double take while you strut the festival grounds. Black to Pink, Black to Green—rock your fav color combo on pasties that change color in the hot and cold. Just like all our other pasties, this color changing fabric is totally waterproof and can stick to your ta-tas for up to 12 hours. Why pick one color when you can have two??? This is the missing piece you need to complete that killer ‘fit!
