This is a formula preparation pot that can be used for formula preparation, warming, and defrosting. I purchased it new and unused on Mercari in April 2025 and used it for 6 months. I will ship the main unit, instruction manual, and box. There are no noticeable scratches or stains on the main unit, but please understand that this is a used item before purchasing. Please refrain from purchasing if you are looking for a perfect item. The instruction manual has some stains. Please check photos 3 and 4. - Product Name: Bottle Warmer - Functions: Formula preparation, warming, and defrosting - Instruction Manual: For use in Japan only Thank you for viewing.
