Even the clumsiest of your friends can sip their favorite beverages without breaking their glass when you gift them the Sttoke "The World's First" Shatterproof Ceramic Reusable Cup. The virtually indestructible cup is crafted out of ceramic that helps keep the drink at temperature for hours on end, a perfect gift for anyone who is an avid coffee drinker and love the idea of a zero-waste (or lower-waste) lifestyle!
