A classic 100-prong bamboo matcha whisk (chasen) with a black thread and an engraved smiley detail. The whisk is the tool for lump-free, foamy matcha: sift the powder first, add hot water, then whisk briskly in a zigzag motion, ideally in a wide matcha cup or pouring bowl. Soak the whisk in warm water for a few minutes before its first use
