Purchased in October 2024 and used for about a year. I am selling these because I no longer need them. Out of the four bottles: Two are made of plastic (T-Ester), and the other two (Snoopy pattern) are made of regular plastic. All four bottles have a capacity of 240mL. The two T-Ester bottles have scratches on the inside from being washed with a hard brush. I believe they can still be used safely if sterilized, but please consider this before purchasing. Please check the third photo. The nipples have been discarded due to wear and tear and for hygiene reasons. Please feel free to message me if you have any questions!
