I wore it a few times and then stored it at home. There are no scratches or stains, but please purchase it if you understand. After cooling the cooling pot in the freezer overnight, take it out and set it in the main unit. Then, add juice, ice cream mix, etc., and turn the handle to make delicious ice cream in a fun way. You can make various ice creams with ingenuity, and you can also search for "Donbie Recipe" on the internet. Although there is no box or instruction manual, I think it has a simple and easy-to-understand design that doesn't require electricity. It is a valuable item because it is no longer manufactured or sold.
