A copper lassi glass is a traditional Indian drinkware made from copper, commonly used to serve lassi, a popular yogurt-based drink. The glass has a wide opening and a broad base that makes it easy to pour and drink lassi. The copper material is believed to offer several health benefits, including aiding digestion, boosting the immune system, and improving skin health. Copper is also known to keep the contents of the glass colder for longer periods, making it an ideal choice for serving cold beverages like lassi. Additionally, copper has antimicrobial properties that make it a popular choice for drinkware, as it inhibits the growth of bacteria and keeps the glass hygienic.
