You're looking at the charcoal Huskee
I adore the Huskee cup, I have had mine a few years now, it is dishwasher safe, lovely to hold, keeps my coffee hot longer. You can even put it in the microwave, I checked with the makers. The best part, it re-purposes waste material (coffee husk) for a sustainable coffee cup.
HuskeeCup features coffee husk as a raw material. The coffee husk is an organic waste material that’s produced at the milling stage of coffee production. Thus using this marerial makes the production of our coffee cup sustainable. By purchasing HuskeeCup, you are helping to recycle hundreds of tonnes of waste material from the production of coffee.
