Pigeon Breastfeeding Realization Nipple for Baby Bottle Used set of 8 (SS/S/M/L, 2 each) These have been used, so please refrain from purchasing if you are concerned. New ones are surprisingly expensive, aren't they? I'm offering these in the hopes that they might be of some help. The boxes are included (only one SS box). As a bonus, I will include a Nishimatsuya breast milk storage bag. It says it contains 60 sheets, but I've used some, so I'll include about 40 sheets. I will ship via Yu-packet Post. To keep the thickness under 3 cm, I will pack the nipples slightly compressed as shown in the last image. This will not affect their use. The boxes will also be folded. The size of the nipples is written on the back of the nipple itself, so please check after they arrive.
