These “Foldz Flat Pens” may be a little tacky looking (depending on how you feel about the Thunderbirds), but they fold up to be less than 1/8th-inches thick. Tipster Anthony suggested they fit perfectly in the back pocket of a Moleskine notebook.
They’re available for $2 apiece. There are Foldz without the Thunderbirds livery, but they’re still in the same glitter-infused plastic in bright colors.

The Farber guy who created these pens used to make a few with lightening bolt and fire designs that were actually kind of cool.
He also makes one in stainless steel and rubber . . . but that one I found difficult to use. It doesn’t fold well, doesn’t lock.
I bought a box of these pens a few years ago. I give one to somebody every once in a while and they always love it. I think the creator’s original idea was that to print company logos on these so you could hand them out at trade shows or whatever. Would make a cool business card.
I’ve had one of these pens tucked into my purse ever since the 5th grade, when my school’s bookstore sold them. It has served me well for the past 8 years.
When I was in middle-school I found it particularly convenient to keep it in the pocket of my Roos just in case I wanted to start writing an award-winning novel on a napkin or something.
