Cleavage Cupcakes are your instant cleavage enhancers! These plump perkers are inserted directly into the bra to give boobs that extra Ooomph! One size fits all, clear in colour, natural in feel, they are made of medical grade silicone and are great at what they do...Oh, and the manufacturer suggests that Cleavage Cupcakes are "not designed for surfing, cliff diving, knife throwing and other extreme sports." Consider yourself warned.
