For this review, I used the sepia brush cartridge, but I am in love with the blood red brush cartridge. Seriously, blood red writing is pretty awesome. The cartridges are available in brush or ball point tips. I have not tried a ball point, so the review is only on the brush cartridge.
The pen is pretty compact, and it is a comfortable grip. The brush is softer than others I have reviewed, so it is more difficult to adapt from a traditional gel or ball point tip to a brush. The sepia is a darker color than other sepia pens I have used, but it is a nice color of brown. There is no bleed through on the ink
Brush is soft
Brush writing is a skill
Overall 3/5 Best used for sketching or brush calligraphy.
