Red Latex Cross or X Nipple Stickers/Pasties. 

These have an overall width of 9.5cm x 9.5cm and a nipple coverage area of around 5cm

Peel the backing paper and save, attach to clean dry skin free of oils and moisturisers. They are not completely waterproof but do stand up very well to water and sweat.

They have a self Adhesive, Hypoallergenic, latex free medical grade sticky back. They can be re-used if you keep the backing paper and re-attach one finished. One this has been used up, you can use eyelash/body glue or tit tape to make them further re-usable.

I have found they stick very very well, please pop a touch of lipbalm over your nipple ends to stop it being a bit painful when removing them. but please keep this to a minimum as oils/moisturiser affect the sticky'ness.

Other sizes can be available, please message to request.
