Coffee is a way of life for us at Wise Men Company. When we saw these amazing enamel coffee cups we knew we had to make them available to everyone. These metal cups are a classic and can be used for so much more than coffee. The enamel paint ensures quick and easy clean up. Not microwave safe, but you can throw them over an open flame if you want. We also recommend that you hand wash and not put them in the dishwasher. CAUTION: Cup and handle get hot when hot liquid is in the cup. Be WISE don't get burned.
