【One-of-a-Kind Item】 Diameter: Max 200mm - Min 180mm, Thickness: 26mm * This item is a slice of a log cut with a chainsaw. * The front surface has been flattened and made parallel using a sander to eliminate any unevenness, and then polished with a 240-grit electric sander until smooth. It has been polished to the level of a paint base, so you can apply surface treatments such as varnish or wax without any further preparation. * The back surface has been sanded to flatten it, but sanding marks remain. * The sides (circumference) have been fully sanded with a sander (electric sandpaper). * Naturally dried, it contains a high oil content, allowing you to enjoy the pleasant scent of Hinoki cypress for a long time. * Oil may seep to the surface, but this can be prevented by applying a surface treatment such as varnish. * Although it has been naturally dried for over six months after being sliced from the log, cracking may progress depending on the conditions of use and storage. ＜About Cracking＞ Cracking occurs naturally due to the shrinkage of the wood as it dries, and cracking may progress further as drying continues. New cracks may also appear in areas that currently have no cracks. However, cracks that have already reached near the center are unlikely to progress further. The product photos may have been taken some time ago, and cracking may have progressed since then. If requested in the comments, we will replace the photos with current ones. Even if cracking progresses, it is unlikely to split completely in half, but if it does split naturally in half, we will provide a free replacement. ＜Notice＞ We also have various sizes available for sale other than this item. If you don't find the size you want, we can also make it, so please inquire in the comments.
