Kinto - Day Off Tumblers 16 oz

From Kinto:

DAY OFF TUMBLER :

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. The bright colors are inspired by a relaxed beach resort and can match well with your day off fashion.

VACUUM INSULATED

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.

Details:
18-8 Stainless steel, Polypropylene, Silicone  - BPA Free
Keep drinks hot and cold for 6 hours (Hot above 69°C / 156°F, cold below 7°C / 46°F)

For maximum insulation efficiency, preheat or precool the tumbler prior to use by filling in a bit of hot/cold water for 1-2 mins.
