This 18 oz Glass is perfect for iced coffee. Included with each 18 oz can-shaped glass is one bamboo lid with silicone rubber seal and a glass straw. Perfect for any type of beverage! We recommend you wash the bamboo tops with dish soap and leave them out to dry. To remove odors, soak the top in vinegar. Mix equal parts hot water and vinegar in a bowl, and let the top soak for up to a 20 minutes. Rinse thoroughly with hot water and towel dry. Use this cup as a part of your daily morning routine, or gift one to a friend!
