Regular Pen Discussion / Pentech Datatwin?

    I used to collect pens when I was a kid but mostly only spun drumsticks. Since recently beginning to spin pens, I found a Pentech Datatwin in my old collection. This pen must have been purchased sometime in the late 80's. I was unable to find any information on this pen what so ever online and the company Pentech has disappeared or something. This looks like a very valuable pen to a pen modder and/or pen spinner.

    Anyways, this pen is balanced pretty well (with the clip removed). It is very light without any mods (will take measurements later if anyone is interested). Also, I will post some pics without the caps if anyone is ineterested as well. The weird looking cap was once clear which I once painted black with a sharpie or something. The pen tips are different sizes because one end is a highlighter and the other end is a felt-tip pen, with removable plastic tips. However, this doesn't seem to affect its balance, so the weight must be fairly equal as far as the tips and marker pen goes. I will probably mod this pen at some point. The barrel and caps seem pretty useful. The barrel might be an exact substitution to a Dong-A (anyone have Dong-A barrel dimensions/weight).

    I'm curious why no one has ever mentioned this pen in any pen spinning/modding sites and what others think about this symmetrical and balanced marker pen (sign pen). Hasn't anyone seen this before?

    If anyone can think of any cool mods to make with this pen, please let me know. I believe I only have one of these pens (I did purchase more when I was a kid, but only one survived that I know of) Come on, I can't be the only one who has this remarkably symmetrical pen?

    Pentech is same company that made the Spinz brand of products. The pen you have there from what i can tell from the picture is probably no where close to dimensions of a comssa. It seems shorter and thicker than a comssa and looks more like a common fat eraser board markers. color twin is quite a bit difference in length build and the caps are totally different. Would need to see the pen next to a well known pen like a rsvp to make any final determinations.

    I'm curious why noone has ever mentioned this pen in any pen spinning/modding sites and what others think about this symmetrical marker pen (sign pen). Hasn't anyone seen this before? It is very similar to the ColorTwin, but its weight is more evenly distributed.

    I'm sure its unavailable in the USA, not sure if there is anything similar in other countries.

    If anyone can think of any cool mods to make with this pen, please let me know.

    Here's a pic with a ruler and an RSVP next to it for comparison...
    The Datatwin is 7.8g (w/o clip) and 1cm diameter (same as rsvp diameter).
    COP=COB (right between the words "DATA" and "TWIN")
    All it needs is a little weight and it will spin pretty good for me considering that I have small hands.
