This is a 20kg portion of slab-shaped raw clay that has been processed in a pug mill. 10kg portions are also available. This product is a brand of clay called Shino clay, but it's not overly "rough" and is easy to shape. More than 20kg is initially prepared, but the weight may be less than 20kg if moisture evaporates and the clay hardens. Wrap the clay directly with a wet towel, seal it in plastic, and once it softens, weigh it before use. The color may appear slightly different depending on the lighting. I may use the same images for multiple listings, so the exact same item may not be delivered.
