Our Instant Volum Esticky Inserts contain Silica Gel. It can increase breast fullness while also keeping your breasts moisturized and attractive, helping you show off your perfect breast shape and improving your confidence. Its use is simple: tear off the protective film on the chest pad, attach it to the inner layer of the bra, heart notch facing up, as described above, fix the chest pad on the other side, and adjust the position of the two sides appropriately. It creates a clear, attractive circumference that makes you more confident and beautiful.
