Basically, these two-pack is highly recommended. The bras fit the opening mechanism works - which I have not tested this with one hand. They are really comfortable. A star (actually, it's only half a) withdrawal, because I had something more dimensionally stable Cups expected and the back like to ride up, so that the bra stays not sit quite where it should. All in all but a small flaw, which is not disturbing in daily life. However, if you want a beautiful neckline, one should resort to another product.
