Haku is a handmade white bamboo chasen (matcha whisk), crafted in the traditional 真（しん / Shin / Zhen）shape. Each chasen is handcrafted through 12 meticulous steps by skilled bamboo artisans, resulting in elegant curves and delicately carved tines. Haku Shin Chasen Width: 6.6cm (2.6 in) Height: 12 cm (4.7 in) Aluminum Case Width: 6.6cm (2.6 in) Height: 12cm (4.7 in) Before use: Before every use, place the chasen in hot water (80–85°C) for 30–60 seconds. This allows the bamboo to absorb moisture and regain flexibility. It improves elasticity, reduces tip breakage and extends lifespan. While using: Rinse with clean water only. Do not use soap. Shake off excess water. Air dry upright or on a whisk holder. Avoid closed, humid storage.
