This is a Silver Clay Horigin start kit. I apologize, but I stopped using it before I fully understood its purpose, so I cannot answer any questions. Please consider this if you are okay with that. If you are interested, I recommend purchasing a new set. I am selling two sets because I started this with my daughter. This one is missing two items. This set cost about 13,000 yen. I attended 8 classes and made 2 pieces, but I quit due to being busy, so I am selling this. A small amount of beautiful silver powder is included as a bonus. The exact weight is unknown. It's also unclear if it's usable. Please let me know if you don't need it. I have blacked out where I wrote my name. I wiped off the stickers, but if it's still sticky, please wipe it again. Please understand that this is used and in 中古 (chuko - used/second-hand) condition.
