This is a handmade item. It can maintain 80 degrees Celsius for 2 hours, making it ideal for keeping food warm. A pot with a diameter of about 27 cm will fit inside. It contains over 300 grams of cotton, making it very fluffy and highly effective at retaining heat. 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. Although it's cotton, it's packed in a balanced manner, but please understand that this is a handmade item. Pressure cookers are heavy and difficult to take out and put away, but since I started using a pot cozy, I stopped using it altogether and got rid of it. Wrapping the pot in a towel and using the pot cozy further increases the heat retention and prevents soiling. This item does not include a cushion. I will include a towel to wrap the pot for those who want one. I welcome questions. Thank you.
