Breastfeeding Consultation Room: Bottles (Glass) 160ml - 2 bottles Bean Stalk: Bottles (Glass) 240ml - 1 bottle Bean Stalk: Bottles (Plastic) 160ml - 1 bottle Pigeon Bottle 100ml All of these were very useful for washing and replacing. Since I was giving milk in parallel with breast milk, the bottles from the Breastfeeding Consultation Room were especially good for developing sucking strength. The slender Bean Stalk type was also good for carrying around, and since I had the experience of breaking a glass one while traveling, the plastic type was also very useful. The Pigeon bottle (glass) 100ml was given to me by the hospital, so it's more of an extra. Please let me know if you don't need it. Nipples are not included for hygiene reasons. If you would like them for size confirmation, etc., I will include them, but please understand that there is no product warranty.
