It is a great gift for housewarming gifts and weddings, and will be appreciated by men and women of all ages. This is a masterpiece that has been carefully hand-polished one by one by craftsmen. It has a large capacity of 450ml and can hold a whole 350ml can of beer. It boasts a thermal conductivity that is 5 times better than iron and 25 times better than stainless steel. When you drink a cold drink using a copper cup, the cooling sensation that feels in your mouth and hands is exceptional. Copper also has a trace metal effect (copper ion effect), which is a property that exerts an amazing bactericidal effect just by mixing it with water. The action of these copper ions prevents the growth of microorganisms and keeps copper tableware sanitary. You can feel the difference from the moment you hold it. Copper has good thermal conductivity, so when you pour a cold drink into it, the container itself cools down, giving you a very refreshing drinking experience. By polishing the inside in a spiral pattern, when you pour beer into it, you can enjoy a creamy foam that goes down easily. Experience the splendor of copper cups with their sophisticated design.
