These sign pens are becoming my favorites, because they feel right in my hand, and write so well. I like broad nibs in fountain pens, but sometimes they put down too much ink. These make a nice broad line, but don't leave pools of ink behind. Plus you can replace the tips if they wear out, or add a highlighter tip, instead of tossing the pen in the trash.

Excellent pens. Best of all, you can buy rubber o-rings and convert these sign pens to accept ink such as Noodler's (see the jetpens article on converting the platinum preppy fountain pens to eye dropper fountain pens - the same o-ring size works on the sign pens). The converted pens produce a great look when you use the electric/highlighter inks (I've tried Lightning Blue, St. Patty's Eire, Hellfire and Year of the Golden Pig). The writing also looks good with regular Noodler's ink (I've tried Ottoman Azure and Gruene Cactus). Since the felt tips are replaceable, the ink options are limitless. Great pen, the tip is fairly fine for a sign pen, and the transparent body allows you to see how much ink you have left... and it's a beautiful pen!

Fantastic as an eyedropper
I did not try the included cartridge. Instead I converted it to an eyedropper and loaded it up with Dr. Ph. Martin;s Black Star HiCard.

I like this combo a lot better than the Sharpies provide at our office for Agile Story Card planning. It makes a bold but crisp line. No wear yet on the tip.

This is just an update and idea-
I took to traveling to class with this pen, and it leaks ink similarly to a fountain pen, such as if you move it quickly or drop it accidentally, then ink will make a Jackson Pollock painting inside the cap or on another hapless object.
A great use of this pen is to take a razor knife and modify the replaceable nib to have more varying angles and widths. (think of a quill pen) This makes the pen much more comfortable and expressive to use.

I did really like the design and performance of Preppy sign pens. In fact, they appear to work very well with converters and Noodler's ink.

However, there's a serious problem that plagues them: the plastic enclosure is quite flimsy. One of the pens I have have already cracked, even though I was especially careful not to apply any excessive pressure.

This is a good pen with a nice, vibrant color. I like that it can be refilled with a color of my choice. The only fault I find is the tip being slightly scratchy.

This pen writes very nice.. however, that's about it..


The plastic is brittle, and since the cap is stopped by the width of the barrel, this has already cracked as others have pointed out. It looks like the inner lining doubles to catch the end without having it wedged tight, but it doesn't. Also, be careful with the refill feature, I barely screwed the bottom to the top, and I can't get it off with normal force, I'm afraid I'll hear a crack if I pry harder...

And yes, the ink is pink.. well.. not really. The ink is red, a nice red, but the pen is too wet. Writing gives you a diluted red, or a 'pink'. If you trace over it about a minute per trace, you will have a nice red line in 3 minutes. Try and rush it, and the drenched paper rolls onto the pen. Does the same thing from cheap .50 per 500 school notebook paper to maruman. Same if you try and draw a filled in circle and aren't perfect. Not worth the hassle. Still looks nice, but I have no use for a pink writing pen.


I tried drying it out, but no use. Still wet and pink. I've been using it for useless things like sign in sheets for students...


Writing - uneven color
Drawing, not so great if you plan on going over the same place twice.
Feels really nice on the paper, until you go over a spot and can feel it dragging.

Could be very good with another brand ink, but I'm not sure..

+ The ink color on this is GREAT!

+ Writes immediately

+ Writes with a lovely, thick line

+ Cheap!

- Tends to eat through ink quickly (due to the marker tip)


I have found I don't use this "marker" as much as I thought I would, and I actually find myself saving the ink refills for my Preppy fountain pen in purple instead. (I have a pink version as well, and I'm doing the same thing with that!)

Still, this is a wonderful purple color and a cheap pen to try out if you are interested in how it works.

got this marker on a whim. and it's incredible! the color is a great shade of purple and it writes so well! next time i order, i'm gonna be getting more of these markers

i like the pen..
but i think i got the color pink :(

Very nice solid, bold, sky blueish color. Writes a tiny bit darker than what *my* monitor shows. Smooth writing, and the pen just looks all-around modern and space-agey. There seems to be a tiny bb in the ink well that, I'm guessing, stirs the ink inside, so shaking it you will hear and feel it. I think it just adds to the space age theme of the pen.

These are an amazing pen and I love the color of the red. They write nice & smooth. By far my favorite pen!

I was hoping for more of a felt tip pen but it really is what it sounds like...a marker :P. These are really noticable, great color, and writes a rather thick line that's not too good for daily writing but for crafts and projects this would be great! I use mine to mark thigns like calendars, writing extra-large notes of the most important things...etc. A nice buy since it's a great color and I can refill as I run out!

Just got my first Preppy Sign Marker in Red. I'm excited about the design since my kids end up using up the red markers in sets first and then I have to buy a whole new set just for the red. However, the color isn't nearly as vibrant as I had hoped for. Any ideas why? Does it just take a while for the ink to intensify?

For the price- this is a steal. The pen tip has a bit of a scratchy feel as it moves across the paper, which I hope changes with wear, but the ink flow is great, and works similarly to the papermate 'flair' felt tip pen. The ink cartridge has a small marble on the end, which when inserted into the pen, rolls into the cartridge and apparently keeps the ink flow moving proper.
Great buy!

Hey owner! Restock please! :)

It's a fine pen but the ink is not black enough. I would still recommend it.

These pens are so cool. i also have the blue and purple ones and they are such pretty colors. this one is really good because i like the shade of brown that it is and it does not bleed through. BUY IT or the other colors... FAST

This color is amazing!!! its one of my favorite pens in the world. If you are considering buying one... BUY IT FAST and NOW!!!

this pen is so cool... the color is so pretty and it writes really nicely... I would definitely reccomend it!!! i LOVE it!!!

I am one of the people who asked for these pens and I am so happy JetPens got them in stock. I just love them!! All of the Platinum Preppy pens are great. Now we just need to get JetPens to order ink refills for the highlighters and these new sign pens, plus replacement points. These wrote a very nice bold line which is fairly fine line for a marker pen. They do not bleed through the paper like Sharpy does. All in all I love them!!

if you are thinking this as a 'Lab' marker, this is not what you think. other than that, it should be fine.
