Silver Clay - I bought this starter kit to learn chogin (silver carving) with my daughter. I am selling two sets. I will also include silver powder. This is an extra, so please let me know if you don't want it. I purchased it for about 15,000 yen. I made two pieces. I have used it about 10 times in total. I am selling it because I became too busy to continue. I cannot answer what each item is used for. I have blacked out where I wrote my name. I will wipe it before shipping, but I had put stickers on the items, so please wipe them if they are a little sticky.
