A set of Yako Oven Clay (2 Kuroki-bushi, 1 Milk), water and oil resistant coating agent, brush, and a book. The clay is new and unopened, but has hardened. Please soften it with water. The coating agent has been opened, and about 1/3 remains. I think it will be enough for 3 bags of clay. The book is a recycled book from the library. You can easily do it with your home oven. - Material: Oven pottery clay - Brand: Yako - Type: Pottery clay - Additional Item: Water and oil resistant coating agent - Weight: 100cc (1/3 remaining) Thank you for looking.
