This is a set of Bean Stalk baby bottles. The thicker one on the left was not a good fit, so it was only used once. I will send it with the nipples attached, but please discard them if you don't need them. The thinner one on the right was a sample, and since my child didn't drink much, it was only used a few times. I think the thinner one on the right is no longer sold, so I used Pigeon slim-type nipples. They worked without leaking. I'm decluttering, so I'm selling them at a low price. Please understand that these are used items.
