These are often referred to as chicken fillets due to their shape. The silicone is soft and supple which not only makes it very comfortable (you hardly know they are there) but it gives a gentle , subtle lift and fills out your bra cup. 
 
It is most popular with people with a small to medium cup size although some people with larger cups use them for a cleavage boost.
The size of the fillet is 14cm x 8cm  by approx 2.5cm thickness at the thickest part
