Stabilotherm has made this wooden cup which has been featured often on the danish DR's Nak & Æd (kill and eat)Tv-Program.
The cup is made in a unique nordic design from Stabilotherm and is made of Beech that has been surface treated. The cup is especially perfect for frost conditions as your lips despite the cold never freezes to the wood like you risk with a metal cup.
Stabilotherm has made a minimodel of it which can hold 2 cl (equivilant of a shot) - perfect for keeping in the pocket, bag or perhaps even keyring. It has a diameter of 4 cm.
Note you should wash this in hand. It does not deal well with soapy scrubs and you should oil it every now and again after wash.
