Mobile device for warming baby bottles at 40℃. Purchased for approximately 2600 yen. Used for about 3 months. The rubber part that supports the bottle is slightly wavy, but I think it doesn't affect usage. It's very convenient because it can be used with a USB connection. - Model Name: Mobile Baby Bottle Warmer - Temperature Setting: 104°F (40°C) - Application: Warming baby bottles - Design: Black, with stripes Thank you for viewing.
