Set of 4 items. Everything in the photos is included. These appear to be high-quality fuchiin (scroll weights), but I don't know what kind of stone they are made of. Product Name: Fuchiin (Scroll Weights) Size: Ball diameter approx. 3.3 cm (green stone) Ball diameter 3.3 cm (red stone) Cylinder length 4.3 cm (cylindrical stone) Ball diameter 4.2 cm (whitish stone) As the name "fuchiin" (written as "calming the wind") suggests, their main role is to prevent hanging scrolls from swaying in the wind. The red ball has obvious damage. The others also have what appear to be cracks, but I don't think they will break easily. I have taken photos of the areas of concern. Please take a look. These are very old items. They were in my grandparents' house. The box is for the cylindrical fuchiin. The other three do not have boxes. They are made of a stone that looks like marble. I don't know the details.
