I found this brush here in Insadong! It is 16 inches long. I think it is beautiful, but I'm not sure yet if it will be good for painting. The bristles are some sort of natural hair, I know because it smelled like an animal when I washed it! It took several shampooings to get the grime and smell out of it. When I bought it I thought it may be "old" since it was dirty, I asked the storekeeper, who spoke little English, who asked the other sales men, who then just laughed! She did tell me that it was indeed "old" --about 2 years old.
