Big Japanese iron cast ashtray with floral pattern

A big sized iron cast ashtray. It is made of Japanese cast iron. It is decorated with a stylized floral pattern, resembling a sunflower. The lid has three big openings.
It can be used as intended, but it will also work great as a mosquito coil or incense burner, or even as a huge paperweight (it weights almost 1.7kg!). There is the name of the maker on the bottom.

Size ca 22x26x3cm. The lid is removable. There are a few small spots showing some rusting.
Please check the photos before purchasing.
