I purchased the attachments intending to use them when going out, but I ended up not using them, so I'm selling them. The Pigeon breastfeeding nipple (母乳実感) is also unused and brand new. Both boxes have been opened once. I purchased both items in September 2025. When shipping, due to shipping costs, I will flatten the tip of the nipple. Please understand this. I will also remove the attachments from their box for shipping. I will fold the box and include it with the items!
