These bamboo matcha scoops or Chashaku (茶杓),  are specifically designed for measuring matcha powder by grams, and it play an important role in traditional Japanese tea ceremonies. 

Care For your Chashaku: To prolong the life of your chashaku, gently wipe it clean with soft, dry cloth after each use. Avoid soaking or using soap and water, as this can split and damage the bamboo. Store in a cool dry place.
