My child didn't take to the slim type, so I haven't used them much. There are 4 bottles in total. I only used size S nipples. The other items are new and unopened. I'll include one nipple brush. I also have a Combi sterilization case! If you'd like it, I can include it for an additional 900 yen. Please let me know before purchasing! Please consult with me about selling items separately. I'll offer a discount for purchasing everything together. Feel free to comment!
