This is a set of baby bottles and nipples that can be used immediately from birth! How about it as a trial set? Pigeon Mother's Touch SS size nipples, 4 pieces Hospital-use 100ml bottles with nipples attached and lids, 2 sets Used for about 2 months with mixed feeding, so there is a feeling of use, but they can still be used. After use, they were sterilized and dried with a steam mate. We do not accept claims or returns. Please ask any questions you may have.
