I received this over 15 years ago. It was already quite dry back then. Due to the sufficient drying period, I don't think there will be any problems like warping. I was told the wood type was Japanese Zelkova (Keyaki), but I'm not sure because I'm not very knowledgeable. Please check the photos. It has become more and more tasteful. You could make it a side table by adding iron legs, not just a floorboard, and it would be one of a kind. If you have a large house, you could carve out the center and use it as a flower vase; it would be gorgeous and lovely, like being in the wild. (Photo 6 is an example of how I use it at home. I have a small house, so I made the stump smaller.) Other uses include a shop sign, a BBQ table, a camping table, a cutting board, and many other possibilities. Please feel free to arrange it as you like. Size: Approximately 57.5cm x 49cm at the longest, Height approximately 10cm There are cracks and knots from the drying process. There is bark inclusion. There are chips and scratches from the milling process. Saw marks and thin bark remain. Please enlarge the images and carefully check the condition of each part. If you have any concerns, please refrain from purchasing. Thank you.
