This is a tire-shaped ashtray. The tire part is made of rubber, and the ashtray part is made of glass. It has the Yokohama Tire logo printed on it. Diameter is 15cm (ashtray part 8.5cm), height 3.5cm. Although unused, I believe it's a Showa-era product. The rubber is still in good condition and can be used without any problems. You could also use it to hold accessories or coins. Perfect as an interior accent to create a certain atmosphere.
