Up for your consideration is this brand new in box W brand 4 ounce glass feeding bottle. It is BPA free.  There was a tiny rip in the plastic on the box I taped over. Also I included will be an 8 ounce glass feeding bottle new in package.

It also has convenient side markings to allow for easy measurement in half ounce increments and milliliters. It also come with white plastic nipple covers which keeps the nipple clean for travel.  Bottles and nipples are dishwasher safe (top rack only).
