The main idea of this concept is to give a new use to a teabag. The calendar teabags designed by Cho Hee Ha are basically a box of teabags with a variety of teas packaged as the dates of that month. Available in Earl Grey and Darjeeling Oolongs flavours, they come in strips that you rip off day by day.
