金不易 Jin Bu Yi Fine Oil Soot Black Inkstick
This is probably one of the most underrated ink sticks on the market today. Rose scented and thick black ink it creates the most easily obtainable shades of grey. They say 5 but I would say more.
Mine broke into three pieecs. But this doesnt bother me. It probably just had a tiny flaw in its makeup or, more probably , someone was investigating the beautiful silken box it came in and dropped it. 
Either way, the ink it creates is slow to make but worth the time.
The incredible shades are wroth ther extra effort. Personally I would reccommend this to someone who paints rather than calligraphs because the results are a very fine grain very soft grey shades.
It works fine for calligraphy, but my personal oppinionm is that it better suits Chinese Painting.
