felissimo Oven Pottery Clay (Everyday Japanese Tableware) ・Kuromame (Black Soybean) Color / Coffee Black Color ・500g (original weight) x 5 bags ↓↓ Please understand and purchase ↓↓ This is felissimo oven pottery clay purchased many years ago, and it has hardened. Although unused and unopened, it is listed as "slightly scratched or stained" due to the changes in condition over time. Regarding reuse, searching online yields methods such as: "Crushing and softening with water" "Wrapping in a wet towel and sealing in a Ziploc bag" etc., but I have not tried these, so please use them at your own risk. ※ I work on weekdays, so I may be slow to respond to comments. Also, it may take a few days to ship.
