I'm on a roll tonight 
This review is regarding both the fountain pen and rollerball Presimo kit from PSI. You can also purchase this kit at woodturningz.com
The kit costs 7.45 for both the fountain and rollerball kit. You can also buy this kit that has an etched design on the cap (costs about a dollar extra I think). 7.45 is woodturningz price, not including quantity discounts or a 10mm drill bit and bushing set (another ~10 dollar one-time expense)
The presimo has a simple, single tube design. I want to make it clear that i freaking LOVE whoever designed the tube on this pen. 10mm is a great size, because you can buy pre-cast blanks of carbon fiber, feathers, and the like. But the real selling point for me is the length, 2.5 inches. As blanks are sold in 5 inch long sticks, you can get exactly two pens out of each one, which is great for making book matched fountain/rollerball sets.
Assembling this kit is pretty easy. You only have two parts to press in: the end cap and the female threads for the nib housing. They are the same size, so it doesn't matter which part you decide to be the front or back.
Photos are available here and here
Now, some people have a negative opinion of this kit. I was slightly apprehensive about buying it because I had read some reviews of people complaining that the cap assembly comes apart with use. I haven't had any problems with this so far, so PSI may have updated their design, but I will edit this post later with more information.
This pen was definitely designed with turners and customers in mind. The Fountain pen nibs that come with the kit (go figure, right?) are some of the highest out-of--the-box quality I have seen as of yet. The cap, instead of being some obscene shiny monstrosity of solid chrome, sports a matte brushed nickel look that acts as a nice contrast piece to both the chrome hardware and the finish on your pen. It screws onto the front, but the male threads on the nib are very far forward and don't get in the way of your writing comfort. The cap press-posts onto the back, again eliminating unsightly threads. The pen is also very well balanced in the hand, even with a heavy material such as tru-stone, you can write with it for extended periods of time and not have your hand feel fatigued.
This pen writes with either a schneider (my preference) or a schmidt rollerball refill. The fountain pens take a normal PSI cartridge and come with ink pumps as well
I definitely like this pen. Unfortunately it is only available in chrome and brushed nickel finish, no gun metal, but we will wait and see
for a seven-ish dollar pen, It is definitely a good value and a good choice for beginning turners (considering other such pens in the same price range)
I will certainly be ordering more of these. I will keep tabs on the cap, but so far, so good.
Enjoy guys! any questions, just ask.
