Nifty little pen, that's exactly what I needed

Received mine today (USA). Works and looks great! We'll worth the wait! Thanks for all your hard work.

Cute, tiny pen

A few days ago I received the pens in Belgium. They look very good :-)

Great weighty feel for small size

Finally received mine 1/3 way around the world. Amaze how easily it writes. Added a -pro because it looked like it will be easier to write with, but as it turned out, the weight & balance or original actually made it more pleasant to use. Great tool!

does what it says on the tin

I'm glad I received the pen at the end of the day and I'm fairly happy with the product.

rapid access inkless pen

Works pretty much exactly how I expected it to. I could see this being useful in emergency situations where you don't have a pen or pencil on hand to write down notes. I wouldn't use this in any sort of official capacity, more for informal notes when I'm out and about. Tiny enough to just keep on your keychain and just forget about until you need it.

Exactly what I had hoped it would be

Exactly what I had hoped and thought it would be. Incredibly light weight last resort pen(cil) for my keychain. You can get a pen that weighs this little but you have to deal with ink drying out. This seems much more like something I can forget about until I think “oh crap, I wish I had a writing tool.” Hopefully is sturdy banging around with my keys. If it is, I am happy. Also, appreciate no lead in the alloy.
