This art piece is a key component in The Bitcoin Executor, but no spoilers here! You have to watch the film to find out why. The main material is birch treated with natural non-toxic oils. The whole thing is held together with steel hardware (and no glue!). The dimensions are 31 1/4″ x 10 1/4″. It’s worth mentioning that the shipping box we use will be the same one from the story!
