Showa Retro Antique This is a Showa-retro ashtray made of TOYO glass. It has been stored in a cabinet at home for a long time. Outer diameter: approximately 13.5cm Inner diameter: 10cm Height: approximately 4.0cm I think it can be widely used as a flower vase, accessory holder, small item holder, incense holder, display, etc. There are no cracks or chips, but since it is a layman's eye, there may be very small scratches that I have overlooked.
