This is a handmade item. The fabric has some distortion, and the cushion fabric was insufficient, so I've used a combination of fabrics, and I'm offering it at a reduced price. It can maintain 80 degrees Celsius for 2 hours, making it ideal for keeping food warm. The cushion is approximately 30 cm in diameter. A pot with a diameter of 27 cm will fit inside. It contains over 300 grams of cotton, making it very fluffy and highly effective at retaining heat. Including the cushion, it contains over 400 grams. Shipping will involve some compression. If using Eco-Mercari shipping, I will ship it as is! The cotton is secured with embroidery thread and buttons to prevent shifting. While the cotton is packed in a balanced manner, please understand that this is a handmade item. Pressure cookers are heavy and difficult to handle, but since I started using a pot cozy, I haven't used mine at all and have gotten rid of it. Wrapping the pot in a towel and using the pot cozy further enhances heat retention and prevents soiling. I welcome any questions. Thank you.
