I wrote about the Pentel Pocket Brush Pen here. I suggested in the post that perhaps the pen could be converted to eye dropper fill rather than use the carts. I find that the pentel carts are pretty pricey, though it is awesome ink. They range from $2 for 2 ($2 per cart whoa!!!) to $ 11 for 6! (Jetpens has about the best price I could find.) Converting this pen to eye dropper amount to a massive savings. I found I went through a cart pretty quickly in regular sketching and using the black to fill in the background.

I loaded it up with some Omas New Gray. Which is a nice pale silvery gray that layers well, perfect for sketching. It is not a lightfast gray so it should stay in the journal and not on the wall. I’ve posted here about turning a pen like this into an eyedropper and this pen is no different. I used a blunt syringe to fill the barrel with juuust under 3ml of ink. That’s 3 carts of ink, in one fill. While I used a dye based ink I could fill it with a pigment based ink as it’s designed for that, which mean it’s even more awesome.

After letting the ink get to the brush I noticed that the ink flow is a little faster than with the Pentel ink. This could be because the Pentel ink has pigment or is thicker than the dye based ink. The Omas Gray ink has good flow even in a fountain pen. I’ll be trying out more inks once I run through this one. The other good thing is that I can fill my black pen up with Noodler’s Heart of Darkness once I run out of carts of black. (Scored 2 more with this pen.)

The best thing about turning this pen eye dropper? It’s simple. All you need is a little silicone grease from the plumbing section of home depot and an eye dropper or a blunt syringe. Money saved? Each fill will save you about $3 over using cartridges.

Blogger's note, I purchased this pen for review and was not compensated by the companies in anyway.
