This is a piece of rolled-up konugi (Japanese oak) that I received from a farmer a long time ago! I've been storing it in a warehouse since I received it, so I don't think there are any insects. This is not a processed product. As it is a natural item, there may be wood chips, dirt, etc. I would appreciate your understanding and acceptance! I will keep it until it is SOLD, so You can contact me anytime. I will add more pictures and accept comments! Please refer to the pictures and if you are satisfied, please consider purchasing!
