What about “normal” and “custom”?

Normal is coated with moisturizer after polishing and crack repair and other maintenance has been performed. The strings are available in three colors.


Custom ones are carefully selected for shape and condition. After polishing, a hardening agent is penetrated to improve the strength of the surface and back surface. A coating is applied for the final finish. Customization improves durability, sound quality, and volume. The strings are available in a total of 21 special colors.
