Super-Stretchable - Teat section has an accordion-like portion that enables it to stretch in response to the peristaltic movement of the baby's tongue.
Ultra-Soft Silicone - The nipple's surface is very soft, yet it does not collapse easily. Made from thick ultra-soft silicone material, the nipple has similar elasticity to that of a mother's actual breast. The dome-like shape makes baby's mouth open naturally, supports its mouth softly and fits its lips gently.
