This is a tea cozy specifically designed for the popular HARIO Chacha Kyusu (Round 450ml). Knitted tightly to fit the size, it can be used without stress even with teapots with short spouts. The two-piece design, with a separate lid and body, prevents the cozy from covering the steam vent. It fastens with a button under the handle. The tea mat is integrated with the body for easy use. 100% Acrylic (Exclusively for Chacha Kyusu Round. Not compatible with Square, Zen, Fukami, etc.) (The lace doily below is not included.)
