I took these out of the box because my due date was approaching, but unfortunately, my baby had to be admitted to the NICU. The baby got used to the bottles used there, so I am selling these. All are new, but I only have one box left. I will pack everything carefully. Nipples for 4+ and 6+ months will be given as a free gift.
