【One-of-a-Kind Item】 Diameter: Maximum 240mm - Minimum 210mm, Thickness: 25mm ・This item is a slice of a log made with a chainsaw. ・The front surface is planed flat/parallel using a sander and polished until completely smooth, then polished to a smooth finish with a 240-grit electric sander. 　It is polished to the level of a paint base, so you can apply surface treatments such as varnish or wax without any further work. ・The back surface has been sanded to flatten it, but sanding marks from the sander remain. ・The sides (circumference) have been fully sanded with a sander (electric sandpaper). ・Naturally dried, it has a high oil content, so you can enjoy the pleasant scent of Hinoki cypress for a long time. ・Oil may seep to the surface, but this can be prevented by surface treatments such as varnish. ・It has been naturally dried for over six months after being sliced from the log, but depending on the conditions of use and storage, cracking may progress. ＜About Cracking＞ Cracking occurs naturally due to the shrinkage of the wood as it dries, and cracking may progress as drying continues. There is also a possibility that new cracks may 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 two, but if it does split naturally in two, we will provide a free replacement. ＜Notice＞ We have other sizes available for sale besides this item. If you don't find the size you want, we can also make it, so please inquire in the comments.
