Your frank green retaining temperature will depend on which of the frank green range you have purchased.
For our Ceramic and Stainless Steel ranges, you can expect hours of temperature retention. Dependant on use, we've seen ice cubes stay frozen over night and hot drinks last for hours. For the best heat retention, keep your lid on and the button closed unless drinking. This is the perfect cup for the sippers of the world.
In our Tap to Pay and Original ranges, you will notice that the difference in material means that temperature retention will be different. We expect these ranges to keep drinks hot or cold for slightly longer than a single use cup. So if you're a fast drinker - these ranges are for you!
