The hand sifter is an ideal accessory for creating a frothy cup of Matcha. Quickly and easily sift the Matcha to prevent the natural effects of clumping. Matcha particles are extremely fine- less than 10 microns (finer than baby powder)- which makes for a smooth drink, but sometimes small clumps may form. The clumping itself cannot be prevented, but the clumps can easily be undone to a fine, beautiful powder using this tool.
