Hospital Direct-Attach Type Baby Bottles 100ml - 2 bottles Wide-Mouth Baby Bottles 150ml - 2 bottles Both are glass products. The direct-attach nipples have fewer parts, making them easy to wash and use! Since they are glass, they are easier to clean than plastic and can be sterilized by boiling, making them hygienic. I believe there are no noticeable scratches or stains, but please understand that these are used items before purchasing. The baby bottles will be sterilized with Milton and then wrapped in bubble wrap before shipping. * Nipples are not included, but we can discuss if you would like them. #Pigeon #BreastmilkRealFeel #DirectAttach #HospitalUse #BabyBottle #BabyBottles
