Using your GSI Doppio Mug is easy. Just open the press-fit lid, pour in your favorite hot or cold beverage, and close the lid. The sip-top is perfect for sipping your drink without worrying about bugs getting in or spills. For hot drinks, enjoy them without the fear of burning your hands. When it comes to cleaning, simply wash the mug and the sip-top with mild dish soap and warm water. Avoid using abrasive cleaners as they may scratch the stainless steel surface. Store the mug in a dry place when not in use. Don't fill it with carbonated drinks as the pressure may cause problems with the lid. That's all you need to know to keep your mug in great shape and enjoy your beverages for a long time.
