In the manufacture of our kits we follow the same technological processes that have been used for many centuries. In the smithy we use charcoal, and when we prepare birch fungus tinder we use ash and water. We package our kits by sewing them using linen, cotton and genuine leather. We do not use plastic or other synthetic materials in our kits. To prepare kindling, we make use of natural jute and flax. Everything in our kits replicates in meticulous detail what people in the Middle Ages would have carried and used every day.
