Sailor Profit Brush Pen - Medium

At first I thought it was going to be a cheap pen as I got it out of its package, because the pen was very light weight for a pen of this thickness. But, boy was I wrong.

For starters, the cap is threaded and screws on to the pen.

I got the cartridge in the pen easily (just as easy as a Pilot Pocket Brush) and waited for the brush to get saturated.

WOW!!! I love this pen. I inked some doodles and I inked a page for my webcomic with it.
I like the way that the brush responds and thus far has been durable.

When I erased my pencil marks and the ink did not fade.
I did color some doodles with prismacolor markers with minimum smearing of the black ink.

I like how black this ink is, i want to find it in a bottle and see if there is a converter for this pen.
Definitely worth the money.

I own 3 Pentel Pocket Brushes, 2 Karatuke no. 8s with converters using platinum ink, and 1 Karatuke sable hair brush pen.

The Sailor Profit Brush Pen is my favorite pen I own.
