Making waves! Great for beginners and coffee heads alike, Kalita's beautiful glass dripper has a comfortable handle and a teal-green plastic collar to keep it in place on your mug of choice and remind you of us. Unlike most pourover drippers which are cone-shaped, the Wave incorporates a flat bottom dripper for better control of water flow. Additionally, the patented wave shape of the filter makes for better temperature stability by reducing contact with the sides of the brewer. All this yields fuller flavor and a more balanced extraction in every cup!
