While in Hong Kong, I was able to pick up both the Pilot Frixion Point 0.4 (similar to a rollerball or gel ink pen) and two Pilot Frixion Colors (which are more akin to a felt tip pen).

I purchased a black and brown Frixion Color from a small stationery shop in Hong Kong called Chun Kee (no jokes please). On paper, the inks were not as dark and opaque as a Sharpie and the erasability (using the friction eraser) would not make these appropriate for labeling boxes or other places where a permanent dark line is needed. But, the erasability did work as advertised which was kind of cool though I don’t know how often I would use it. An advantage of the lighter inks is that it did not feather or bleed through much on my standard notebook If you’re looking for a felt tip pen that does not bleed through on the average notebook paper and is erasable, this may be just what you want.

One unusual quirk that I discovered between the Frixion Colors and the Frixion Point is that the eraser tip on the Colors was on the cap so you need to post the cap on the end to have it available as you write. Alternately, on the Frixion Point, the eraser was on the end of the pen body so if you post the cap, the eraser is hidden. I don’t necessarily say one method is preferred but I find the inconsistency between models a little odd.

Now, let’s talk about the Frixion Point 0.4. I purchased the blue-black model which had super smooth flowing ink and a sharp thin line comparable to a Pilot Precise V5 which is my go-to big box pen for ease-of-use and quality for the price. The Frixion adds the ability to erase to the equation making it a great option for notes and rough drafts. The ink quality alone is enough to recommend this pen, the eraser is just a bonus.
So, for what purposes would you use these pens?

Final word:
Pilot Frixion Point 0.4 in blue-black. Recommended. $3.75 US
Pilot Colors in black and brown. Interesting but not sure of its usefulness. Maybe a bright color like orange or yellow to annotate notes might make this a useful tool but the black and brown seem to serve little purpose for me. $1.75 each US
(This pen was tested on the Miquelrius medium flexible 300 grid paper book purchased from B+N.)
