Using these Coquette Round Spiked Pasties is easy. Just peel off the backing from the self - adhesive part and stick them on your skin where you want. Make sure the skin is clean and dry for a better hold. When you're done using them, gently peel them off and store them in a cool, dry place. They're reusable, so you can use them multiple times. Avoid getting them wet as it might damage the adhesive and the leather. If they get dirty, you can gently wipe them with a soft, dry cloth.
