Thank you for viewing. I purchased this as a spare, but it seems I won't need it, so I'm selling a new, unopened one ^_^ Unlike the Pigeon Peristaltic Nipple, this nipple can be used from newborns to 6 months, so you don't need to buy new ones every month, which is economical♪ ▶︎NUK Plastic Baby Bottle 300ml. Nipple ▶︎ Brand new, unused, unopened It will be shipped via Takkyubin Compact. Although it is new and unused, please understand that it has been stored at home.
