Nipcomfort Seamless Stick on Bra & Nipple Cover

Bought online from nipcomfort for a holiday because they have triangle shaped covers that are waterproof. Wrong size for me but they don't allow returns or refunds. They're large, which was recommended for D+ cup sizes, however I think that depends heavily on your back size. I'm a 30G and they were way to big for me. I personally think they're a D+ cup size for a 36" back and upwards. Paid £35 for the set of 3; 2 circles and 1 triangle shape. They come with a little travel bag, too. They're in perfect condition; have only been tried on and once I found they didn't fit, didn't bother unwrapping anything else. They're in the lightest colour: honey. I'm not sure about the material, but they feel like a silicone. Happy to take offers! :)
