Precision Oiler Pen 0.8mm

Made like a low cost version of a technical drawing pen. Similar to the photo shown but not quite identical, the reservoir of one I received lacks a reinforcing metal band found on the real drawing pens, but compare the cost. The 4 star rating takes into account the cost. Only seems to work with low viscosity oil and dispenses quite a small quantity of oil. From ordering to receipt took just less than 48 hours, so good service there.
