These are brand new Boomba inserts designed to boost one cup size. They’re sticky on both sides, and are designed to be worn in place of a bra when you’re wearing something that won’t work with a regular bra. I accidentally purchased the wrong size, and they can’t be returned. The box has been opened, but the inserts themselves have not been removed from packaging or worn at all - as soon as I opened the box and saw the label, I realized I’d ordered the wrong size. Boomba doesn’t accept returns. These are brand new, still in the original packaging/wrapping, and unworn. PRICE IS FIRM.
