Review: I love every aspect of the Moonman 2 - I love every aspect of the Moonman 2. The glass eyedropper which is included makes filling the MM2 a “no fuss, no muss” event. The eyedropper fits perfectly in the ink reservoir and ‘voila’, it’s ready to write, the filling time needed is about the same as installing a cartridge and I think shorter than a “piston” do-hicky pen. The inner ink space of the MM2 is vast, seems like a few times of that of the capacity of a cartridge OR piston provides. At its widest point the MM2 is about a half an inch (12.7MM), the ink reservoir is about 2 inches long (51MM), resulting in an ink reserve of about half of the entire pens physical volume. That is a lot of ink. The fine nib (pun intended) glides, making for a smooth and consistent writing experience. I used Pilot Iroshizuku Shin-kai (Deep Sea) dark blue ink. The MM2 never skipped, blotted, blobbed, scratched or stopped getting the ink on the paper in a fine line, in fine fashion. The MM2 posts fairly snuggly, however will disengage with the slightest pressure. The disengagement is not due to a design flaw, but rather due to the super smooth acrylic body. MM2’s fine nib may have convinced me to convert from my normal fountain pen diet of a medium nib. The fine nib by definition results in a fine width of ink on the paper, line with less dramatic flair than a medium nib lays down. The clean & uncluttered design of MM2 reminds me of the famed Fisher bullet space pen. This design affinity may explain its MoonMan name. If the MM2 could write in zero gravity, astronauts may begin composing lyrical space soliloquies using the MM2. The clear, high polish acrylic body is tapered at both ends making it visually well balanced (although not perfectly symmetrical), and showcases the color of ink you dropped in. This brings a fun aspect to the pen since the color of the pen IS the color of YOUR ink, so you participate in determining the final appearance of the MM2 by your ink color choice. I love the opaque plastic “presentation box”, which can be repurposed into pen/pencil carrying box. It is well made, sturdy with a secure locking tab. There are no branding marks on the box except the high quality construction which matches the pen, which is a big plus for me. It’s a box that can be used, not put on display or stored in the closet. The MM2’s thin metal branding band comes in any color you like, as long as it is red. While the MM2 is perfectly fine as it is, I do wish the MM2 had a cap option available with an integrated pocket clip. Likely a conscious design decision, I don’t think it would dilute MM2’s brand or design integrity and would increase its mobility. It is clear; the Moonman 2 is a great pen, especially when considering its price. I am thinking of getting a few more Moonman 2 pens so I can fill each with a different color to match my changing writing mood.
Review: A gorgeous pleasure to write with - I absolutely love this pen. Firstly, it is beautiful to look at and to hold. I filled it with Thornton's Red ink, in the customary manner of matching the pen to ink color, and it is just a wonder to behold. The clear acrylic is luminous and sets off the translucency of the deep red ink creating an almost magical effect. I also really like the solid acrylic caps on both ends. They capture and bend the light in ways that are delightful. I also really like the red band with the MOONMAN brand printed across it. It's not my custom to be a brand loyalist. I learned my lesson with Apple. But MOONMAN has definitely won me over. I'm officially a fan. In terms of how it writes, I have come across nothing negative whatsoever. It just works. Its got a nice even flow. It never skips of fades at the edges of the letters. The feel of the gold colored steel nib across the paper is smooth and comfortable. I've only had it for a few days, and I've been writing with it more or less constantly, so I don't know how it will respond to being left alone for a an extended period of time. But I'm confident it will be fine. There are some aspects of it that some people might not like. Over the course of the first day a bit of red ink crept its way onto the lower edge of the nib, under the "section" as I've heard it called. And sometimes a bit of condensation gathers on the interior of the pen cap when it's screwed on. Neither of these issues concern me much. At first I was bothered by the ink on the shaft of the nib, but it didn't last. It doesn't take away from the overall beauty of the pen. I think this is a great pen for a beginner, and a great pen for a long time collector. I will likely acquire more expensive pens in the future. I've been eyeing a Visconti Homo Sapiens, but I really can't imagine liking an expensive pen all that much more than this one. It is a very beautiful, highly functional, incredibly affordable object. I don't think you can ask for much more.

### ⭐⭐⭐⭐ Beautiful Pen and Unique Design
*by L***E on May 24, 2019*

EDIT: I bought a replacement extra fine nib unit and fine from an ebay seller and it wrote perfectly so I'm guessing the one I bought here that came with the pen was a fluke. Looking at all the units, I noticed a trend that each nib was seated slightly off from the feed — a manufacturing characteristic it seems as the grip section has a special groove for the nib to slide into which was constantly slightly off from the groove the feed slips into in the grip section on all the units I bought. This leaves roughly 1mm play with an inclination towards inexact seating. While this isn't a problem as it doesn't inpede proper ink flow, it's something I noticed. (see pictures) Additionally and more noteworthy is the poor threading quality between the barrel and cap. It's functional but not at all as satisfying as other screw cap fountain pens I've used. Then again, they did cost more. All and all, the design is very unique and the writing experience is still enjoyable for the price, it's a good buy but it hasn't changed my mind on Chinese fountain pens. Currently inked with Platinum Lavender Black, my absolute favorite. PREVIOUS REVIEW: The pen is beautiful, flawless and looks rather fancy. When I tried writing with it, I was disappointed to find that the nib was awfully scratchy. I'd still buy it again if given the choice but you may want to consider using a different nib. Not sure what the size is though. Fyi, the kaweco clip fits it rather nicely. I got the idea from posts I saw on reddit. It makes for a nice addition.
