A copper glass with lid is a drinking vessel made of copper material that comes with a cover or lid to protect the contents of the glass from spilling or dust. The lid is usually made of copper material as well and can be a simple cap or a more decorative lid with intricate designs. Copper glasses with lids are commonly used for serving hot beverages like tea or coffee, as well as for storing and drinking cold drinks like water or juice. They are also popular for use in traditional Indian households for serving lassi, a yogurt-based drink. The copper material is believed to have health benefits, as it can help with digestion and boost the immune system.
