Thank you for viewing. These are Pigeon brand nipples for baby bottles. This is a set of 3, including 2 size SS and 1 size S. [Usage History] SS ① → 2 weeks SS ② → 1 time S → 1 week I am selling these because I didn't use them much as I was breastfeeding. Please note that they will be flattened for packaging when shipped. *No price reduction. *No returns, so please understand before purchasing.
