Our minds generate endless ideas every day, some fade, some matter, and only a few deserve to stand out. Tombow MONO EDGE Duo Pen is designed for that moment of selection and it helps you decide what deserves attention and what should remain in the background.
A dual-tip tool built for clarity, it combines a 3.8 mm chisel highlighter for strong emphasis and a 0.4 mm fine liner for precise notes, details and structure. Both tips are powered by a single ink reservoir, ensuring consistent performance until the very last drop, no imbalance, no wasted ink.
Filled with fast-drying, water-based neon ink, MONO EDGE Duo Pen is clean, reliable and designed for everyday use across journals, notes, planning and study. It brings order to information and transforms writing into a visual system where ideas are not just written, but organized with intention.

Beautiful colour. The nib is smooth and wet. The grip section is textured, I will not worry about writing with it in hot weather. This is my first demonstrator pen, I love watching the ink level drops (very slowly) in the barrel. The package is packed very securely. Thank you staffs at Pen Venture.
Bought a Gravitas Monster. Kept in pen sleeve in padded case. Used carefully. Treated carefully. Filled twice. Noticed ink all over my hand. No obvious problem. When home I emptied the pen and notice a thin crack in the barrel at the "turning knob" end, just before the aluminium. Now unusable. Ink seeping out. Complete waste of money. Complete crap. Either desire flaw, or poor materials or both. Watch out. Will never buy another Gravitas POS, nor from this retailer again.
I skipped the original aluminum Monster mainly due to fear of slipperiness. I've had issues with other aluminum pens and I seem to recall multiple reviewers mentioning such with the aluminum Monster. I heard no such complaints for the stone washed titanium one so I eventually went for it. I'm glad I did!
The large broad nib is silky smooth, the matte finish comfortably grippy, the vacuum filling system well made and the ink capacity very impressive. The body is nice and thick and feels suitably hefty. I also like the look of the matte finish. Matte doesn't seem to be quite as common in fountain pens as all kinds of shiny finishes (which can obviously be great too!) so it's nice whenever it's an option.
I'm not used to pens without any kind of roll stop but at least on my shall we say busy desk the Monster is quite safe from falling. I'm not sure if the Ultem in this one is supposed to be sturdier than the acrylic in some other versions or not but better be safe in any case.
Shipping was quick and secure and included a traditional handwritten letter from Emy. Thank you!
The construction of the Vac 2 is flawless. The textures of the materials and it's simple lines display an elegant beauty. The large steel nib delivers a pleasant writing experience and also provides a bit of flex.
Amazing Pen! Gravitas makes one of the best piston fillers out there. I dont keep the nib and normally use the pen for coustom flex nibs with Jowo #6 compatible nib units. So, i really cant speak on the nib. However, this pen is just built with high quality components. The weight, feel, and overall aesthetics are unmatched. You wont find better at this price point.
I recently acquired the Platinum Maki-e Sansui pen in a Medium nib. The Pen Venture team was kind enough to carefully inspect and tune this pen before sending it on to me. Many thanks for that. It writes very smoothly and with a steady flow of ink. The Medium nib is my favorite nib configuration from the Platinum brand. The line width is nice and thin and always writes consistently right of the box. This lovely Maki-e pen was no different. I highly recommend it.
