These Pastease are great for waterproof swimwear, fun tan lines, and for wearing under sheer tops! When properly applied, Pastease will stay on in most conditions. Simply remove oils and lotions from skin, peel off backing, and stick on dry nipples. Gently remove at the end of use. To reuse later, place them on a clean mirror or window and re-apply with spirit gum. Have fun with what you wear no matter where you wear it! Smiley. Dimensions 3 inches.
