The pen body is constructed of four parts, tip, body, bolt assembly, and cap. The clip is a deep carry that is sandwiched between the cap and bolt assembly. My clip came loose in the box. I simply tightened as much as I could by hand. If it loosens again, I will put some blue loctite on the cap threads and retighten. I also replaced the supplied ink cartridge with a Otho PG-M05NP. Which is a fine ceramic roller gel cartridge. The ad says it is compatible with Fischer SPR4 cartridges. I have also run a Parker fine point gel ink cartridge in it.

Pros
1. Price Retail is $29.99 with a current market price of $27.09
2. Common ink cartridge availability
3. Quality machining and conistent anodizing.
4. Bolt action is smooth
5. No branding on the pen.
Cons
1. Some might find the pen slippery
2. Cap might loosen on you resulting in a loose clip.
Overall, for $27.09 this is an inexpensive pen that is worth the asking price. I admit, I did not test the supplied ink cartridge, but my experience has been that the Chinese ones leak and are splotchy. So I simply replace them straight away. So factor that into the final price. Also, with all bolt pens, keep an eye on the bolt lever. Over time they can become loose.
