To Go Click Thermo Mug. There are many insulated mugs for enjoying a sip of coffee or tea on the go, but few can be operated blindly like this one: Stelton has optimized the centrally located click valve. Once opened with a finger press, the rim can be positioned for drinking at any point. The insulated mug thus promises a 360° instant enjoyment experience—no more annoying twisting of the thermos mug to find the opening. Additionally, this easy-to-grip insulated mug keeps hot drinks hot for an extended period and cold drinks reliably cold (0.4 L). Perfect for a morning coffee shot on the go or a refreshing cold drink after a workout. Stelton offers the To Go Click Thermo Mug in a robust stainless steel design with a color-coordinated plastic lid.
