Pigeon Pochitto Bottle Steam Sterilizer and Dryer Used from June 2024 to approximately 10 months. Regularly cleaned with citric acid, but visible stains remain. Please check the condition in the photos (underside of the lid, bottom of the container, heater part, lid seal, etc.) Due to the condition of the stains and the need to replace the filter, the price is lower than the market average. Only those who understand this are welcome to purchase. No instruction manual or box. Please understand that this item is stored and shipped by an individual.
