Q: Are nipple covers reusable?
A: Silicone covers are, many times over. Wash them after each wear, let them air dry and store them on their backing sheet so the adhesive stays clean.
Q: How long do nipple covers last?
A: Several months of regular wear if they are washed and stored properly. They need replacing when the adhesive no longer holds after cleaning.
Q: Can you wear nipple covers instead of a bra?
A: Yes, that is what they are for. They give coverage under sheer, backless or strapless styles where a bra would show.
