Review: Great little pen - I needed a pen to use when I wear polo shirts with no pockets. If I am wearing a shrit with a pocket, I usually carry a fountain pen, but those pens can get separated from the cap when not in a pocket. This pen did the jog nicely as it is small, lightweight, and handy to use. It write beautifully every single time. That being said, there is not much ink in the cartridge and I am not sure how to change the cartridge once it does run out. Aside from that, it is working beautifully and the bright orange color means I am not likely to leave it behind.
Review: Great item - I recently had the opportunity to use the Tombow Pencil BC-AP54 Pressurized Oil-Based Ballpoint Pen in the vibrant Orange color, and I must say it's been a pleasant writing experience. First of all, the pressurized design of this pen sets it apart from others. It allows for consistent ink flow, even if you're writing at different angles or on challenging surfaces. This feature has proven to be extremely convenient and reliable, making it a go-to pen for a variety of writing tasks. The 0.7mm tip size strikes a perfect balance between precision and smoothness. I found the pen glided effortlessly on paper, creating clean and consistent lines without any skipping or smudging. Whether writing notes, journaling, or even doodling, this pen delivers on its promises. The orange color of the pen adds an extra touch to any writing experience. It's bright and eye-catching, making it easy to spot in a pen case or on a cluttered desk. Plus, the pen itself has a sleek and comfortable design, with a non-slip grip that ensures a comfortable writing experience even during extended use. Additionally, the oil-based ink used in this pen is bold and vibrant, making a statement on any page. The ink dries quickly, preventing any potential smearing or smudging, which is always a plus. Overall, the Tombow Pencil BC-AP54 Pressurized Oil-Based Ballpoint Pen, Air Press, 0.7 in Orange is a reliable and enjoyable writing tool.

### ⭐⭐⭐⭐ Good field pen
*by M***X on February 5, 2023*

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. İt 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.
