Your frank green temperature retention will depend on which of the frank green range you have purchased!
Due to the vacuum-sealed insulated technology of our Ceramic range (or Stainless Steel range - this range is no longer sold online), it should keep your drinks hot or cold at a controlled temperature for much longer, given that you do not open the lid or press down on the button. For the best heat retention, keep your lid on and the button closed unless drinking.
This is the perfect cup for the travelling sippers of the world that like to make a hot cuppa and take it with them in their bag for sipping at their destination.
In our frank green 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!
How long it stays hot or cold for will depend on the volume of drink, the temperature of your initial beverage and how often you release the seal by opening and drinking from your frank green.
