Writes with a typical ball-point blue, I'd call it true blue. It is very fine, I
would guess .15 mm when writing with a light touch. While nail-ish, it does
write quickly and smoothly, and does not leave blobs behind. It is sometimes
sluggish to start, so test it before important writing. Once it gets going, it
It is ideal for tiny writing in a pocket planner or calendar. Unfortunately, it
is too fat to fit in the leather pen loop on my planner. The pen is 9 mm in
I mainly write with fountain pens, but they are no so hot for my planner. I will
carry this as my "stunt pen" for borrowers.
Very nice writer with the included black ink cartridge. The Violet color is very
dark, more of an eggplant. My only knock is that it does not post well -- many
times the cap has fallen off and now the finish is chipped on the cap. If you
jam it on hard it will stay.
I use this pen daily with other pens in rotation with various colors. It starts
up every time and writes with a light touch.
I bought this to replace one chewed up by a dog. The plastic was sort of
rubbery, so the pen did not splinter and injure the dog. It's a pretty, yet
tough pen. I use it as an eyedropper pen, filled with Platinum Sepia.
The EF is more of an F. The previous pen, also an EF wrote medium.
It is a lovely emerald green. I loaded it with Noodler's Green Marine as an
eyedropper, so even the clear body is deep green. I added a nickle clip to match
the silver nub and cap jewel. It writes smoothly and reliably. As an eyedropper,
it writes a long time. However, when the ink fill gets below one-third, it can
get drippy, so watch out.
I also have a Kaweco Sport Classic demonstrator (all clear) as an eyedropper
with Platinum Pigmented Sepia. It has been great through three refills.
this is an additional review to note that South Sea Blue is now Inspired Blue. I
have run two full eyedropper loads of this ink through my Platinum Preppy with
03 nib ("fine"). It is the fastest, smoothest pen/ink combo that I have. it is
great for high-speed note taking.
But beware, this is is not in the least water-resistant. Spill water on your
writing and it will be gone!
Freaky on black
On a black background, it starts out looking weak and watery, but as it dries,
it becomes lighter and more opaque, and quite readable. On a white background
it looks pale green and stays pale green. The pictured cap color is pretty close
to it in action.
It writes about 1.2 mm wide, so more like a medium Sharpie than a chisel point
white board marked. It erases easily with a dry tissue.
I would recommend it for black, but not white background.
Quite a handy case. Right now I am hauling 11 pens, markers, skinny dry erase
marker and pencils (all fat). Two more pens could fit in. The flip-over divider
sort of snaps into the back so my pads of Post-Its can't escape. The color is a
vivid orange, tending towards the red-orange and darker than appears on the
screen. The fabric is a little shiny, and so handsome. A handle or loop would
have been good, but with my big hands I can carry it easily.
Instead of the included cartridge I use used a Platinum Carbon Pen Ink
Cartridge. So far both are working great, even though the Carbon Ink is not
recommended for the Preppy. Of all my Preppies (6) just one has cracked -- a
Preppy Sign pen. Elsewhere a Preppy entusiast has recommended reinforcing the
cap with Scotch Tape before it cracks. She said after it cracks, don't bother --
it won't work.
