The Kinto Day Off Tumbler 500ml is designed for a relaxing yet active day off. Vacuum insulated, it retains the temperature and flavor of drinks for a long time. With a rounded handle that is comfortable to hold, it is perfect for carrying around on walks or day trips. The cap feels smooth on the mouth and is structurally designed to stop ice cubes and hot drinks from coming out vigorously so you can drink comfortably until the very last sip. Double walled stainless steel tumbler prevents heat transfer with a vacuum between its inner and outer walls. The foil layer covering the inner wall reflects heat back inside, contributing to excellent heat and cold retention. The bright colors are inspired by a relaxed beach resort and can match well with your day off fashion. In addition to usability, material and texture support long-term use. Made of durable 18-8 stainless steel, the tumbler does not rust easily. The colored tumblers have a powder coat finish on the surface which prevents scratches.
