I would like to buy some dolsots as a gift. I went to koamart.com but have a couple questions.

They sell the stone bowls with or without a lid. The dolsots with the lid have a metal band and the ones without the lid don’t have a metal band.

Do I need a lid for bibimbap?

What is the purpose of the metal ring/band? Is it better to have a pot with one or without?

Thanks
