Birch is a slender, fast-growing tree with thin bark. A Birch is also a bundle of twigs used for flogging. Guess which one we’re using here? This Rattan Birch consists of thirty Rattan Canes that are each approximately 1/8 thick, 24 long, and bundled together with Artificial Sinew. It’s safer to use than actual birch because Rattan doesn’t shed bark or embed twig nodes in the skin. Be sure to soak the Rattan Birch in warm water for a few minutes to soften the reeds and reduce the possibility of breakage. A full set of instructions is provided.
