About 2 years ago (maybe more) I ordered a Ti2 Designs Techliner (titanium) pen. Just love, love, LOVE the design of this pen, and solidly made! It came with a Scripto cartridge in it. I inquired with Ti2 designs because I wanted to use the Pilot G2 cartridge in the pen. At the time (Mike) said they didn't have a solution for the G2, but they did have some conversion pieces for the Pentel Energel series of cartridge. That made me happy, but I still wanted a G2 to fit in this pen, because I just love the G2 writing ease. Energel is close, but it's not a G2. Time went by, and two things happened: 1.) The Pentel Energel system cartridges improved significantly. Now I'd say they might even be as good as the Pilot G2, but Pilot still has more colors. 2.) Ti2 finally developed a converter system for the G2. This is important, and I'll explain why in a moment. If you do any shopping around for pens and/or refills, you will see millions of people out there screaming endlessly for pens which will fit the G2 cartridge...and there just aren't any (which makes no sense to me, especially now, after all this time of millions clammering for just such a thing. The only (decent) pen which will fit a G2 is, go figure, a Pilot Metro pen. (Sure the plastic G2's will all take them but why would anyone do this? More to my surprise.) And, there's a reason for this. You see, the G2 refill is different from most pen cartridges. With most other cartridges it's just an OAL (over all length) issue and the refill can be trimmed to fit most pens...but not with the G2. The G2 has this collar around the ferrule on the front of the cartridge which prevents it from fitting in most pens. In some pens it will fit, but it fits badly. And, unless you can fashion a hollow spacer with the exact O.D. of the collar you are screwed and can't use a G2. This is why there's no pens that fit the G2 (regardless of what some pen companies will tell you). Unfortunately though, it's more complicated than just this. The spacer must also have two different inside diameters, and while most people might be pretty ingenious, this isn't something you're going to easily do in your garage / basement (unless you have some machining tools). One end of the spacer has to be sized to fit around the collar of the refill while the other end needs to be able to stabilize the point. Without this, the refill either doesn't fit, or if it does the tip moves around (bad ju-ju). Welp, the wizards at Ti2 figured it out and my kit arrived today (after traveling around the world about 5 times because of the dang USPS, delayed by about 45 days). Took a few minutes to take the pen apart (and if you own a Techliner you know what I'm talking about with all the magnets, spacers, o-rings, and precision washers. Because the neodymium magnets are directional you have to get them in the right way, but they also have a mind of their own because they grab onto anything and everything in the process. The back end of the pen isn't too hard to do once you figure out the magnet direction, but the front part can be kind of puzzling at first with all the pieces (some go in, some come out and some stay in...and others stay out). Anyway, got it together and it works GREAT! I'm now in business with the absolutely stunning and cool Ti2 Designs - Techliner pen - complete with G2 cartridges inside to supply the ink! Yay! (and hope this helps someone thinking about a Ti2 Techliner, but wanting G2 capability). P.S. - All told, this process took two years to complete. So, I'm a pertty happy camper right now!
Glad this solution came available for you. The Techliner is a great pen. I’m a fan of the Uni Jetstream, so I’m fine with the original refill, but it’s nice to have options.
In some respects the fact that it took so long to travel this path, now I'm somewhat disappointed about a couple things. One is the fact that Pentel Energel pen technology has evolved quite a bit in the past couple years. And now it seems Pentel actually has more available colors than Pilot. Part of my original reasoning for liking the Pilot system better was the available colors and line weights. Now Pentel has them beat. Secondly, the Ti2 Designs Techliner pen is a pretty technical design, and it involves several powerful magnets. These magnets raise havoc with pen cartridges, especially metal ball cartridges. Apparently the magnetic field influences the flow of ink around the ball leading to some skipping and dry starts. Now that I've finally found my solution, sadly, I'm actually looking for a different system. <sigh> Such is life I guess.
