Residing in Lake of the Hills, Il , Lyndsey, owner of The Cozee Shack designs and hand makes each of our ceramic mugs. Don't they look like a metal campfire mug? YES!!! They do, but they aren't. If you have ever drank from one of those mugs you'll know why we opted for the ceramic version instead. These bad boys are made to last but not suitable for the dishwasher or microwave! Cheers to your drink, and mug, of choice!
