Coasters made from leftover flooring material given to me by a carpenter. They are approximately 10cm by 10cm, and 1.5cm thick. The wood is Japanese cypress (hinoki), and it has a very pleasant fragrance. The edges have been trimmed with a router. The surface is coated and smooth. The underside has grooves, so cold cups won't stick. The shape is irregular with slightly rounded corners. There may be small scratches. I think they're perfect for use in outdoor settings. These are upcycled items, and are priced to sell. I hope you find them useful.
