Haiwan tea factory has done it again! They have taken the old and tired mini tuo and re-invented it! These mini square bricks are 4.5-5 grams each and are lightly compressed. You can steep for just a short time and they will literally melt apart in your gaiwan or teapot. 2011 fermented tea was used to produce these single serving mini bricks! You won't taste that fishy funky factory smell in these, they are smooth and rich all the way!
