A handy little box containing 6 Medium Sticks measuring approximately 5-6mm in diameter. This is the most popular size that we supply. Please be aware that willow charcoal is a completely natural product made simply from the willow grown on our farm. Therefore the sizes of the charcoal sticks are approximate measurements, one end of the charcoal stick will differ in size to the other end. Look very carefully at a stick of willow charcoal and you will see the marks where the leaves have been removed from the willow stick and also the soft central pith at the core of the stick.
