Pigeon Glass Baby Bottles Set of two: 240ml and 160ml. (Retail price: 240ml 2860 yen, 160ml 2750 yen) I also used plastic bottles, but the glass ones were easier to use because the milk cooled down faster. It was also good that I could sterilize them with boiling water or disinfectant without worrying about deformation or deterioration, since they were glass. I used them only a few times because I was mostly breastfeeding. I will sell them to someone who understands that they are used items. Thank you.
