All bone products are basically played like this. As long as your hands are not dirty, you don't have to wash them deliberately. You should play with them every day. Love sweating, a summer person, should play as little as possible at this time, avoid sweating too much, and dry it in time when sweating. Avoid contact with water, sunlight and acidic substances.

It is recommended not to oil the bones, as this will easily blacken the appearance, and it is difficult to turn the bones into a natural luster with jade texture. You can grind the bones properly with a cloth tray first, not excessively. If the bone is made too bright, it will lose the original feeling of the bone and the attractive luster of the bone after the patina is hung on porcelain.
