"KANTAN" means "easy" in Japanese. The Kalita Kantan is a folded paper filter that fits over your mug - giving you a portable one cup brew that gives you a clean tasty brew.
Add about 12g of ground coffee into the filter, pour slowly over a period of 3 mins 200ml / g of water and enjoy your single cup brew.
And just wait until you feel the paper filter - we've never seen such smooth, shiny and fine paper used as a filter!
