The set follows the traditional grading system of SHO-CHIKU-BAI (Pine-Bamboo-Plum), with Pine being the highest quality and Plum the most basic. Each set contains two short strings (1 cm x 59 cm) and two long strings (1 cm x 98 cm). All pre-orders require a minimum of 3–4 weeks for processing, excluding holidays.
