It’s November already and it’s time to prepare for the winter. This warm set of heaters called “Brr” is especially prepared for cold, winter days. Heater “Brr” is made out of wool and does a few actions at the same time: insulates hands from the hot cup, keeps the heat and warms frozen hands. There are also two silicone band inside the heater to prevent it from sliding down the cup. Such intersting idea belongs to designer from Poland Beata Faron.
