I bought these for my daughter, but she didn't like the nipples, so she didn't use them much. There are no noticeable scratches, but there are some marks left from washing. I sterilized them in the microwave. ⚫︎ChuChu x 2 (plastic, 240ml) with lids ⚫︎Combi x 1 (plastic, 240ml) with lid Both are microwave safe. The nipples are for all ages.
