Review on Sakura 30181 Pigma Micron Blister Card 01 Ink Pen, 0.25-mm, Black: Precision and Perfection in Writing by Hannah Curi

One of the best ink sticks I have ever used. I always try to get hold of it, as does the Micron 03. The Micron 01 ink pen is a very thin needle that's great for sketching or drawing small details. I think 03 or 05 works best for filling large areas. If you have a heavy hand when drawing, be careful as the tip can break if you use too much force. I have found that this pen can last anywhere from a couple of months to a year depending on how often I use it. It doesn't dry quickly, which is a plus. This ink pen can also be used with water, but it doesn't smear or move with it - just slightly. I have attached a picture I drew with this Micron 01 ink pen.
