This is a handmade item. There are some imperfections in the fabric, and the cushion fabric is slightly short, so I've made adjustments and am 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 centimeters in diameter. It can accommodate a pot with a diameter of 27 centimeters. 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, it will be shipped 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. I used to find pressure cookers heavy and difficult to handle, but since I started using a pot cozy, I no longer use them and have gotten rid of mine. Wrapping the pot in a towel and using the pot cozy further enhances heat retention and prevents soiling. I welcome any questions. Thank you.
