Thank you for viewing! ✨ This is a Pigeon Breastfeeding Realization baby bottle. I purchased it new in October of last year (2024) and used it for about 3 months. I used multiple baby bottles in rotation, so each one was used 1-2 times a day, and I washed and sterilized them after each use. Having three would make it convenient to reduce the frequency of washing them ^ ^ ✨ The nipples are two size S and one size M. Please be aware of this. I used both S and M sizes from when my baby was a newborn, but the only difference was the drinking speed, and I didn't even realize the sizes were different until I put them up for sale (^_^;) Compared to new ones, there is some wear and tear, but the frequency of use wasn't that high, and the condition is clean ✨ Since they are made of glass, I will wrap them in bubble wrap and pack them in a cardboard box for shipping. If you have any questions or would like to negotiate the price, please feel free to comment ^ ^
