I have one extra, unused, and still in its original packaging baby bottle because my child has outgrown it! I will fold the nipple for shipping, so the box is not included. I will ship via Yu-Packet Mini. (The box can be folded and included as well) I always have the problem of having one left over when they come in packs of two, so if you're having the same problem and only want to buy one, please consider this!
