I'm selling these because I no longer need them. There are some minor scratches from use over time, but they are still perfectly usable. The numbers on the measurements are still clear! The Snoopy one on the left was used for about 4 months. The one in the middle was used only once. The one on the right was used for about a year. The one in the middle is glass, and the others are plastic. The nipples are relatively clean. The middle one is M size. The ones on both ends have L size nipples, but if you don't need them, I can ship them without nipples, so please comment if you prefer that.
