KeyUnity KP00 Titanium Alloy Bolt Action Pen with Bonus Refills, Retractable Pocket Ball-point Pen for Everyday Use Signature, Fine Point, Black Ink (Stonewashed)

This pen exudes quality – its weight, texture, and feel speak of its durability. Despite its small size, the writing experience is superb, with long-lasting ink and a distinct quality in every stroke. While its size might pose a challenge for some, it’s perfect for my usage, attached to my keys. In terms of durability, this is my second purchase; the patina it developed over time fascinated a coworker enough for me to gift my original one. Considering its price point, it’s hard to find anything that matches its quality. Having tried numerous products, each with their flaws, this pen stands out as a great value purchase.

Just what I was looking! Fits perfectly in the elastic pen holder on my Spigen passport wallet. Ideal short length and medium/small width. Appreciate the high quality titanium material. Five extra ink cartridges provided. High recommended.

It's definitely a sturdy pen. I click it all day and nothing gets loose. It's a bit small if you have larger hands. Came in a cheap plastic case but that didn't matter much to me. Just gives me a place to store the refills at work. My only gripe is it was a little costly but I do enjoy the pen. Writes smooth as well.

I was pleasantly surprised by the quality of this pen. I had been searching for a very small solid brass pen with a bolt mechanism for a while. I had only been able to find the mini bolt action from BigIDesign. But with a price of $70+, I wasn’t willing to commit.This is real brass that has begun to show a patina and lots of character. The material is sufficiently thick and has a good weight. At first the mechanism was a little stiff, but after mindless fidgeting it is now very smooth and easy to deploy the pen.The only issue I foresaw was a lack of pocket clip. With one tool I was able to modify a widely available clip to fit. For this I used a Clío sold for the Fisher Bullet Pen. These are sold individually and widely available for under $5.I used a pair of standard pliers(not needle nose) to carefully and incrementally squeeze and reduce the circumference of the clip until it was able to positively grasp the barrel of the pen.Note: go slowly and frequently check the size before squeezing further.Place a thin rag or paper towel over the jaws of the pliers to avoid scratching the paint.

very nicely built for such a small pen! great bolt action and smooth writing . great value here!

The pen is made well with quality materials. It is solid and has a good balanced weight. The biggest draw backs are that it is too skinny and short for comfortable writing more than a few quick notes. I was also hoping to attach a clip to it so I can carry it at work in a pocket but due to being to thin the standard clips do not work.

Wanted a small pen for my keychain.Ordered kp04 but just slightly too big (bottom).This is kp00 (top) and is perfect size, and no pocket clip. Both use the common d1 pen refill so easy to source replacements, but came with a few extra. The kp00 also came with several extra 0 rings, kp04 came with just 1. Good idea to thread lock the parts still though.

It's smaller than I thought it would be, but it's nice! The brass is great and it still has a nice weight. Definitely put a keychain or lanyard on it though, since it's very easy to lose.
