What do you call pens that are opposite of retractable?

I have a pen that I pull apart to use. It works oppositely of normal retractable pens. Retractable pens have a end which must be pushed in order to write. This pen must be pulled apart in order to write. I'd like to get more of these pens, but I don't even know where to begin to find them.

1. Ask Yahoo Search. It will tell you.
2. do you know the brand of the pen? if you do you can start from there. if you don't, try google and type in pens
3. If you know the brand of the pen, you could probably contact the company through a toll-free number or on their website to get information. Maybe do a search of "pull apart pens" ... ...other than that, i don't know. good luck!
4. I'm guessing it might be called a collapsible pen, or a collapsing pen.
