The KINTO Travel Tumbler is designed for a comfortable drinking experience wherever you go. Made of durable stainless steel with a sturdy texture, the surface does not scratch easily. Vacuum insulated, the tumbler has great heat and cold retention. The wide opening makes it easy to drink from, put in ice cubes, and clean. The cap feels smooth on the mouth and is designed to stop ice cubes and hot drinks from coming out vigorously, ensuring stress-free drinking until the very last sip. With a compact form and a leak-proof lid, it is ideal for carrying around.
