How do I prepare a new brush before using it for the first time?

New Japanese brushes arrive stiff, coated in a water-soluble sizing that protects the bristles' shape during shipping. Before first use, it's essential to remove this sizing completely.

The best method is to rinse the brush in water. A light rinse under running water works well. Avoid soaking the brush in a container for extended periods.

To preserve the brush's performance and lifespan, dry the tip carefully. Water reaching the base can weaken the adhesive and cause bristles to shed. After rinsing, hang the brush with the tip pointing downward to dry.
