He sells this pen for $15 with free shipping. He also sells a demonstrator Platinum Pen with a similar fiber tip but without free shipping. Since I didn't have any experience with these, I opted for the cheapest route to give it a try.
The pen comes with two disposable tips. Somewhere I read (on his post?) that a tip should give you two fills of ink. Each tip costs $2, and you can buy them from Engeika. According to the Ebay listing, this pen (and I'd imagine the tips) are only available in Japan.
I inserted the tip and filled the pen with a Noodlers Purple color (for the life of me, I can't remember the name and I don't have the bottle with me, but it doesn't seem to be made anymore. It isn't an eel or fastdry). I filled and unfilled a few times, and it seems to hold quite a bit of ink.
I would have preferred to have written this review after using a tip all the way through. I haven't made it through a complete fill yet though. The ink comes out heavy - like a marker would. It bleeds heavily through molekskine paper, and it stays wet (and smudges) for some time. It feels nice to write with, and if you want a broad, solid line, this pen is great. For a signature on some 65lb paper, this pen would be excellent. I haven't had a problem with feathering, although I haven't written on heavy rag content paper yet.
Generally, I can't find reasons to use it all that frequently.
The pen is small, coming in a bit under 5", but its got a little chunkiness to it. Its a conservative black with gold colored furniture. I prefer big pens generally, but this thing isn't too bad, and you can post the cap. Its got a basic stylish look to it, but simple. Sort of reminiscent of a MB 146 in shape, but considerably smaller.
By the way the ink soaks the tip, I can't imagine that I can change colors without replacing the tip - then again, I haven't tried yet.
Generally, I think its a cool little pen, and worth $15, particularly if shipped free (EMS from Japan can get expensive). When I change inks and tips, I'll post my experience with it. Nonetheless, if you'd like to add something a bit different to your pen collection, then this pen should be fun.
