Easily best color lead (0.5mm) available. Uni ball and Pilot eno color leads
disappear from aper's surface after some time while this lead still stays on
paper visible in my case forever. Since color leads are not really graphite,
they are more fragile but I never have problem with them as they are not
designed for pressing hard on paper anyway but light touch is needed and let out
only 1mm of it through the pencil tip.
People having trouble with 0.5mm color leads ought use 2mm color leads from
Being new to the colored lead fad I decided to buy the three biggest brands of
0.5mm lead. Staedtler Mars MIcro (blue), UNI-ball (red), and Pentel Stein (red).
I wanted to buy each brand in red but mars was only offered in blue.
Erasability: Both the Pentel and Mars leads were impossible to erase and act
like an indelible pencil. The UNI however erased as easy as normal graphite. (I
tried using both normal pencil erasers as well as the premium hi-polymer
Durability: Both the Pentel Stein and the UNI appeared to be fairly comparable
in their durability (the UNI may be slightly stronger). The MARS lead reminded
me of those 2 foot long rubber pencils that you use to play with as a kid (huge
The left handed smudge: writing more like an indelible pencil both the MARS and
Pentel appeared to be resistant to smudging. Although the UNI smudged noticeably
less than a standard graphite lead it could not compete with the other two.
Color and depth: Both the Mars and UNI appear to write with a deeper and smooth
feel while the Pentel offers a slightly more crisp feel.
Overall I am most impressed with the UNI however will be investing in the Pentel
because I need an indelible pencil for work.
I initially bought this lead as a prospective alternative to the uniball colored
leads. Yet, I was quite disappointed with the quality of the lead. Though it
may leave a mark a tad darker than the uniball colored leads, it only does so
when it does not break. this lead is much too brittle for any practical use.
If the lead is advanced a millimeter too far out of the pencil it without fail
Though this lead may provide 2 extra pieces for 30 cents, it is no alternative
to the uniball colored leads.
