Thank you for viewing. We use natural Japanese oak, which is a favorite of stag beetles and rhinoceros beetles. It is from Kagoshima Prefecture. The materials are mainly sourced from mountain forests where rhinoceros beetles and stag beetles can be collected. This product is not suitable for drilling by us because it is already quite dry. It is an unprocessed product except for cutting. Please check the condition in the photos. The product condition is new and unused, but due to the natural wood, please understand that we cannot accept claims regarding any dirt, etc. 【Notes】 Due to the natural wood, there may be bark peeling, drying cracks, insect bite marks, etc. Returns and exchanges are not possible to prevent any trouble. Also, please purchase after you are satisfied with the product. #JapaneseOak #Oak #ClimbingWood #Ivy #RhinocerosBeetle #StagBeetle #Gecko #Hollow #Quarium (Stag Beetle Aquarium) #Cabrium (Rhinoceros Beetle Aquarium) #Kunu (Japanese Oak)
