[Precautions when polishing]

・When sharpening, there is a risk of scratching and damaging your hand. Please be careful when polishing.

- Rinse off the abrasive that comes out while polishing with water from time to time, remove moisture with tissue or kitchen paper, etc., and check the surface being polished. If you continue polishing without rinsing with water, the polishing agent remaining on the surface may damage the surface of the jewelry. Please change the water accordingly.
