I purchased these at Babys R Us on December 2, 2024, for around 2000 yen for both, but my baby wouldn't take them, so I'm selling them. ^_^ Both have only been used 3 or 4 times. They have been sterilized by boiling before and after use, as per the instructions. - Brand: BIBS - Size (Nipple): SIZE 1 (0-6 months) - Material: Natural Rubber - Packaging: None - Instructions: None - Product Name: Color Pacifier Feel free to ask any questions or negotiate the price in the comments. ^ ^
