I purchased the baby bottle a year and a half ago and used it for about 5 months. I purchased the size S nipples about 2 months ago and used them about 10 times. Overall, it's clean, but the white cap has small scratches when held up to the light. (They are small scratches that don't show up in the photos.) I am selling it because I switched to exclusive breastfeeding. Please wash and sterilize before use.
