Customers say
Customers find this pen to be a fantastic writing instrument that performs well under various conditions and is comfortable for extended use. They appreciate its sturdy construction with a spring-loaded clip that holds tight, and consider it a good value, particularly as a pressurized pen. The size receives mixed feedback – while it fits easily in pants pockets, the ink cartridges are very short. The color also gets mixed reviews, with some finding it great-looking while others note the colors seem underpainted.

Great pen!
I have purchased 2 of these pens. I like the smaller size. They are well made, easy to grip, not heavy but really has the feel of a good pen. Refills are easily accessible and inexpensive. Being able to write at any angle in my job is important.

Good field pen
This is defiantly a field style pen. Neither necessarily tactical nor for office use. But with nice and simple outdoor details. It writes well for a ballpoint pen. It is an on-the-go pen that you could take with you every where. Flexible wire clip on this pen which opens almost 30 degrees, gives you a-lot of options in terms of where to clip the pen. When I opened the interior of the pen I noticed that the ink container is almost the half size of an ordinary ballpoint pen. But you could replace them when finishes. With the exception of clip and spring it is made aut of plastic and it is a light weight pen. I bought the orange one to be more visible in my bag. Ä°t has a rubberize material that increases control when you hold it. It writes at every angle as mentioned. And yes, on wet paper too, depending how wet your paper is! To summarize: it is a good pen and feels more reliable for those times that you pull the pen out and you fear it is dry or won’t write.

They write almost anywhere.
Each time you click this pin you add a little pressure to it so it doesn’t run out if you write upside down you can ride on just about anything like wax paper there’s a little opening on the fan if you look real close and that is put there so that if you’re in a weightless environment you won’t lose your PIN you can tether it to yourself and the pressure will overcome the weightlessness. Cool stuff huh? Only problem I have is they write a little too thin but I can live with that especially enjoyed them when I work in rehab and had to make notes and I can get a lot more in a note is because of the thin line. It’s just a good all around utility pen. Tombo makes some good higher end stuff too deserves a look all of them do..

Good looking pen with a great clip
This pen has the most functional clip of any I own. The spring loaded clip holds tight and works great to clip on thick materials like jeans pockets and backpack straps. It travels with me at all times and I will pick up a second to leave in the car.I have the clear version which shows the ‘airpress’ mechanism at work and looks really interesting without being too industrial.I have large hands and the pen just fits me. There is a raised V-shaped notch that is designed to hold charms and dangles on the pen. When I write, it sits on the webbing of my thumb and helps keep the pen gripped in place rather than being uncomfortable. If a charm were attached, it would rest by the palm of your hand rather than dangling around. I think it is a well thought out detail and good design.Writing is reliable and fairly smooth. Much less skipping than a space pen and the roller gets less ink buildup. It is a very thick pen which works for me but may be a consideration if you have small hands.
Yep –

I make written notes on a daily basis, on varying surfaces and in different positions. This pen copes with my task. The clip is robust using offset hinge points and thick wire, there is also a loop for another lanyard. The pen is light but has a solid feel. I am happy with this pen, it is great working pen.
