This beehive is a pre-assembled two-story set. Additional boxes without pre-drilled holes are also available! Please purchase only if you are able to provide a review immediately upon receiving the product. The hive boards are made of cedar. Burning the surface of the cedar boards is a method to carbonize the soft wood surface, providing protection against decay. "Yakisugi" (burnt cedar), which has been used for exterior walls for a long time, has a carbonized surface, making it resistant to decay and less prone to rot. Due to the difficulty of procuring materials, the roof, top board, and bottom board are not included. Please prepare them yourself. Japanese honey is a luxury, priced at 10 yen per gram.
