【#1 on Rakuten, 8 Awards!! / Recommended by Midwives / Recipe Supervised by Registered Dietitian / Comes with Great Bonuses】 Kocokara Bottle Warmer Milk Warmer Bottle Warmer Bottle Warmer Bottle Warmer Insulation Formula Pot Liquid Milk Baby Supplies Newborn Preparation Baby Shower Nursing Supplies Baby Gift KMW-001 Currently, the same item is sold on Rakuten for 6980 yen, so this is a great deal! It eliminated the hassle of making milk in the dark at night. I had my husband set it up before bed. It was kept warm, so there was no waiting time! When the baby cried, I could feed them immediately! It was very stress-free. I stopped using it because I switched to exclusive breastfeeding and no longer needed it. The operation is fine, but please refrain from purchasing if you are concerned about home storage.
