These are three polishing skills, one is sashikomi（traditional polishing）, one is kesho（modern polishing）and the other is basic polishing. Our products are all made by sashikomi normally and the sashikomi is divided into three levels：A / A+ /A++. If you only need kesho or basic polishing, it can be $400 cheaper for A class, $800 cheaper for A+ class, and $1500 cheaper for A++ class.
