This is a set of two 160ml baby bottles: a Pigeon Mother's Milk Realization and a ChuChu Slim type. They were used for about six months starting last November and were stored in a dark place when not in use (both sterilized by boiling). There are minor scratches due to use. *Please note that the ChuChu bottle is originally a slightly orange-tinted bottle. This is not due to milk staining. Also, the nipples will be removed and shipped separately for hygiene reasons. Please purchase them separately. Please purchase only if you understand the above.
