Set of 4 silicone nipples for baby bottles, large flow. Rounded tip, gentle design for babies. Used a few times in rotation. In excellent condition. Please use with KR-100 and KR-200 hospital-use baby bottles. Even for larger babies, we recommend SS size at first. When the baby's feeding amount increases and they can drink quickly, switch to these large flow nipples (for babies 3500g and up). On average, around 6 months old. - Quantity: Set of 4 - Material: Silicone - Shape: Rounded tip design - Application: Baby bottle nipples When shipping, to reduce thickness, they may be slightly compressed, but they are made of rubber, so they will return to their original shape. Thank you for your understanding. Thank you for looking.
