NEW/NEVER USED IN ORG BOX WITH ALL PARTS. The world’s first fountain pen section having a rollerball tip with tungsten Carbide Ball. The MegaT InkballT Writing System will give you the flow of a fountain pen with the control of a roller ball. Each InkballT point will last for about one kilometer of writing. The MegaT InkballT draws ink just like a fountain pen! It uses a cartridge converter or standard international ink cartridge. Fill through the InkballT point, fill the converter separately, or use an ink cartridge. MegaT specific design, heavy-duty, spring-loaded, color matched jewelry-grade chromium mask. CAP & BODY : Hand-turned, hand-made, high-density acrylic resins, close tolerance threads for sure closing and engineered MegaT colors for a luxurious look. TRIM : Strategically placed, color matched, jewelry-grade chromium. A rollerball that takes fountain pen ink — too good to be true? Not in the case of the Mega Inkball. After the very first fill, it wrote smoothly and, after the first sentence, skip-free. The set comes with one barrel and cap, four nib sections, a small jar of black ink, one ink converter, and two standard, international ink cartridges. The resin barrel is handmade, and luxuriously thick and curvaceous (maybe too thick for some hands). The metal trim and clip are chrome-plated (“jewelry-grade, ” according to Monteverde). A high-quality touch is the spring-loaded clip. Overall, the pen feels tight and solid. The tungsten carbide rollerball appears to be foolproof. Ink flows smoothly and consistently even as I changed writing pressure and speed suddenly. The line weight remains virtually consistent as well. The only hitch came when switching from very heavy to very light pressure. For the next few strokes, I got some breaks in the line. The inkflow is conservative, too, producing a fine line and less bleed-through compared to either standard-nib fountain pens or inexpensive rollerballs. Since the Mega Inkball is, at heart, a fountain pen, you must take all the usual precautions of working with fluid ink: Don’t carry it less than 100% full on airplanes; watch your fingers when filling it from an ink jar. The four included nibs are identical. Each has a lifespan of about 1 km of writing (which translates to roughly 200 handwritten pages).
