Wave Tsubame series is a collaboration with Tsubame city, a place that famous for high quality metal tableware production in Japan. The engraved mark "Made in Tsubame" shows this dripper is proudly hand made by experienced craftsman in Tsubame city that never compromise on quality.
Tsubame series keep using the classic three holes design, but instead of putting the bottom support in middle like other version, Kalita reduce the diameter of dripper's bottom and use a "ring" to support the filter. That keeps filter away from the bottom holes which leads to a smooth flow rate.
