Zebra Penpod Mini Keychain Ballpoint Pen - 0.7 mm - Black Body - Blue Ink

Very cheap, very compact as a keychain pen, looks quite good yet simple. My only complaint of these pen is its tendency to accidentally "eject" the pen. I have already lost 2 of these due to that. Hopefully they'd be able to add a screwcap feature just to be sure...

Amazing pen for a keyring. Best one I've ever used because it's so short and easy to carry, yet expands to a reasonable length. I immediately bought several in different colors because I wanted to be sure I'd always have one handy.

I did have the problem of the pen opening by accident and lost a couple that way. Finally solved the problem with an o-ring (from the local hardware store) that fits around the top of the pen just below the wide end part. The o-ring narrows the gap between the pen and cap so that it takes a little more effort to push them together to release the cap. It has worked perfectly ever since.

O-rings in basic black are a perfect match for the black penpod, but I've never seen o-rings in colors. So I use small rubber bands that match the colors of the caps, and with several twists around the pen, they make passable substitutions for o-rings. I found tiny, bright colored rubber bands in the hair accessories department of my local pharmacy that work quite well.

The pen itself is a great little pen - writes smoothly. The problem is that the latch isn't secure. I bought this for my husband as a stocking stuffer, and it really came in handy until one day he noticed that it was gone. It must have unlatched. We wondered if/when the pen would detach and get lost when a few weeks earlier he found it lying on our front porch. So, it was great while it lasted.

Great pen for your keychain. Im always in need of a pen, and usually never have one on hand. Since I always have my keys on me, having the pen on my keychain comes in handy. One of my favorite pens by far.

Sidenote: The Sharbo Gel refills are perfect fit for this pen if you desire a gel ink and great colors.
