Our large crates are packed with kiln dried birch logs. A large crate is approx.2.0 x 1.10 x 0.85 in size extrernally with a loose volume of 2.70m3 with each log inside being approx. 25cm in length. Birch is super easy to light and kicks off heat almost instantly. Birch burns really well with a nice fiery flame, great for log burners, fire pits and pizza ovens. Whilst smelling amazing when burning. All of our logs are kiln dried and have a moisture content of less than 20%.
