They're somewhat reusable, more of a bra pad but don't leave a particularly natural shape.
These work fine if put inside a hard-cupped bra. But they don't have much of a natural shape (I saw they were triangular in the pics, but the curve is not particularly natural, and is amplified if you've got A-cup breasts). The sticky material sticks pretty strongly, it can be removed without damage but you've only got a handful of attempts before reusability becomes an issue. Material seems pretty good, but again, it needs to be put in a fairly sturdy cup.
