This is a massive burl from a large Mizunara oak tree that was felled in August of Reiwa 7 (2025)! It looks great for handmade crafts or interior decoration. It's a one-of-a-kind item, so don't miss out! I believe the weight is around 13 kilograms. Please feel free to comment if you have any questions or would like to negotiate the price! Thank you for looking.
