SMOOTHERPRO Bolt Action Pen with Tungsten Side 3 Colors for EDC Pocket Color Black(TP156)

I love this pen. It has a nice size, great weight, well constructed, true stainless steel. The grip is much better than it may seem at first glance. It accepts Pilot Frixion ink refills, all sizes. 0.5, 0.7, and 1.0 mm refillables. It is roughly the same size as your normal pen, but because of the weight of the stainless steel, it rests much more comfortably in your hand. When you hold it, you actually feel like you're writing with something with quality and not just a cheap plastic pen.That all said, I do love the pen. However, I've bought two of these, but had to replace one and then opted out of keeping the second one. This is only because of the ink that came with the pen had been slightly depleted and was dry. I wasn't sure if I couldn't get the ball rolling in the refill or if it really was just that dry, but it happened twice in a row and from the first pen I bought to the second pen, the first came with the ink in place, an additional refill, and a second tip that will erase, assuming you're using Frixion ink.The functionality of the pen is as expected, but I have to say that I really enjoy the mechanism that retracts the pen tip into the body of the pen. For some reason, once you get comfortable with the motion, a regular clicking pen just feels inadequate.If you want a nice pen that isn't completely overdone, this will last you until you lose it. Stainless steel, in my opinion, is better than aluminum, and I prefer it to titanium just because of the cost. Titanium is stronger and lighter than stainless steel, but because of its composition, it's significantly harder to work with, which is why it's much more expensive. Aluminum won't hold up as long as stainless steel will and the weight just isn't there.

I’ve had my SmootherPro Bolt-Action Pen for a few days now and want to add my initial short-term review on it.As suggested by others here, I’ve added thread-lock to the pen to help prevent the lost of components.I also added a tiny drop of fine oil to the bolt mechanism and this has significantly improved the smoothness of the bolt action which initially was a bit gritty out of the box.I can not speak on its “tactical” qualities, or about the tungsten tip, except to say that it is pointy, and that I am confident that either ends of the pen could do serious damage to a human.In my experimenting, I have found an excellent gel ink refill to replace the original ball-point refill. More on that later.Pros:- The pen appears sturdy and feels good in the hand. It is 14.2 cm long, by 12mm wide.- It has a nice balanced weight. The aluminum body has some heft, but not overly heavy.- Nicely finished in a semi-matte black paint.- No hot/sharp edges except a little edgy-ness to the L-shaped bolt hole, but this doesn’t get in the way or make it less fidgetable for me.- Bolt-action satisfies my fidgeting nature.- None to little rattling when shaken.- Good value and a fair price at ~ $14.Cons:- The clip is ok, and does not have sharp edges, but is on the inexpensive side.- Original ball-point ink refills (2) that came with the pens are also ok. Nothing to write home about.- Not necessarily a con, but the bolt-action is not silent. There is a nice positive click when using it after it is oiled and broken in.- I wish the Parker refills would fit without having to sand the end caps - even though this was easily accomplished. Maybe this was just an issue on my pen sample? See below.One suggestion for those of you who may prefer GEL ink over ball-point is the Parker QUINK GEL refills. I bought the Black Medium 0.7 size and these can be bought from your favorite office-supplies store, or here on Amazon:https://www.amazon.com/PARKER-QUINK-Ballpoint-Refills-Medium/dp/B001AFB6YI/ref=sr_1_2?keywords=parker+quink+gel+black&qid=1582061529&sr=8-2Note: The QUINK GEL refill is just a smidgen wider at the end cap compared to the original refills. 5.9 vs. 5.7mm. You may need to, as I did, simply use fine sandpaper and very lightly sand the black plastic end cap of the QUINK GEL refill to make it fit properly in your pen.This same QUINK GEL refill also fits perfectly in my Parker Jotter ball-point pen, too with no sanding.Overall, I am enjoying my SmootherPro Bolt-action Pen. It is a good writing instrument with my preferred GEL ink replacement, sturdily built, suits my fidgetability, and comes at a relatively inexpensive price point. I would recommend this bolt-action pen to my budget-conscious friends and family.I hope this review and photos has been of some help to you.

The pen is sturdy, well built, and simple to strip down and clean. Why clean? Well, after the first ink cartridge stopped working, I loaded the second, which leaked, badly. Parker quinkflow inserts didn't fit well. The ball tip has to be forced through. Pulled a generic, same shape one from POS pen I had, and it fits. Going to keep looking for a proper refill. Pen great, ink sucks.*update* After wrestling with different generic pen refills, and having several leak (the refill separates where the barrel meets the end, likely from when I close the pen. It closes pretty hard.) , I purchased some Fisher Space Pen refills. The tips did not go through the tip of the pen. Couldn't even force it. Luckily I had a drill press and an xy vise. A couple of different drill bit sizes and the space pen inserts work wonderfully. I use this pen every day at work, and carry it with me everywhere. No further leak problems after several months and a lot of abuse.
