Purchased at Akachan Honpo. This is a 3-way bottle sterilizer case. The box and instruction manual are all included. It's a 3-way sterilizer: liquid sterilization, microwave sterilization, and storage case. We used the microwave at 500W for 5 minutes. After sterilization, it becomes a basket, so you can drain the water and store the bottles directly, which was very convenient. In addition to baby bottles, it can also be used to sterilize pacifiers, sippy cups, and breast pumps. The inner basket has a handle, so you can take out the bottles from the liquid without using tongs or touching the liquid with your hands. We used it for about six months, so there may be some scratches, but it's still in good working condition. Condition: Used (used for six months / sterilized) There are some minor scratches. Please refrain from purchasing if you are sensitive to imperfections or are looking for a perfect product. Type...Baby bottle related goods
