SERMICLEBra Inserts 4 Pairs, Bra Pads Sewed Stitched Removable for Sports Bra B/C,C/D & D/E Cup Optional

I don't wear sports bra's but a slightly padded regular 1's. Will the pointed top of these move up, and show?

Can't see reviews?

What are the diameters of the three product options?

what is thickness? Will it add a full cup size?
