Tombow FUMI
^(From the sea to stardom.)
- MODEL:
Tombow FUMI – model SH-FM11
0.5 mm (only available in 0.5 mm)
- MATERIALS:
The FUMI is one of those mechpens defined by its materials. The body and the eraser cap are made of Nagori™, a composite material derived from seawater minerals, developed by Mitsui Chemicals. It’s hard to describe how it feels, but think of something between ceramic and a plastic resin, very cool to the touch. It has a matt finish, like non-polished resin, (very) slightly coarse. The pocket clip is stainless-steel and the cone tip is metal (tin?). Internally, though the lead tube is plastic, the FUMI has perhaps the most beautiful full-brass clutch that I have ever seen. And as expected, the spring is stainless-steel.
- ERASER:
Though I l-o-v-e Tombow’s erasers (in fact, I’m using a MONO zero ULTRAFINE right now), the erasers they supply for their mechpens are sad. Not that the rubber compound is bad - in my opinion it’s almost as good as the MONO zero that is right in front of me. The problem is that it’s ridiculously small 🤦♂️.
- MEASUREMENTS:
The FUMI measures 143 mm from tip to eraser cap, and has a fusiform body. Right below the pocket clip it has a diameter of 11.3 mm, that tapers to 11 mm around the middle of the body and then to just 7.5 mm right at the cone tip. Though I was expecting something much lighter, the FUMI weighs 19.6 g (!). It is slightly tip heavy, with the center of mass located at 66 mm from the tip.
- FEATURES:
As I said above, what the defines the FUMI is the use of Nagori. Other than that, it’s a general-purpose (dress?) mechpen with no mechanical feature.
- AESTHETICS:
Sober – that is the word for the FUMI. It is discreet and has a classy air to it, so I think it looks great. The writings on the body are engraved and not printed, which gives it a more refined look. The seam, between both parts of the body, is REALLY fine, you can almost miss that it has two parts. With all that, I think it’s safe to consider the FUMI as a dress mechpen. Tombow offers the FUMI in Stone Black (this one), Sea Blue, Shell White, and Sand Gray. In my eyes, Stone Black is THE color for it, especially because the others are not homogeneous, so there might be some contrast between the upper and lower parts of the body. Mine, however, looks almost as made of just one solid piece. According to Tombow, because of the manufacturing process, no two FUMI are identical, which in my mind is a plus.
- ERGONOMICS:
Fantastic! Not only the dimensions, weight and weight balance are great, but the Nagori material feels great in my hand. Interestingly, it feels cool to the touch, and after using it for a while it doesn’t warm up as what you see with plastic or even metal. For people with sweaty hands, I’m sure that is a plus. However, in terms of traction it’s not very grippy, so if your hands do get sweaty, maybe it will become slippery.
- MY THOUGHTS:
When I bought the FUMI, I wasn’t certain what to expect. Honestly, I bought it because it was something new from Tombow, so I got essentially for collection purposes. Nonetheless, to my surprise, I enjoyed using it much more than I expected. Though I usually favor drafting models, the FUMI would be a pencil I would look forward to using all day long. It just looks great, and more importantly, writes great. If I had to say something negative about it would be the puny eraser. Yet, many other models are guilty of that same fault, and besides, I always prefer to use a pen eraser, so for me at least it’s a non-issue. All that said, the FUMI rocks. If ever Tombow releases the FUMI in other calibers, it would be a must-buy for me. Yeah, I really liked it 🤩!
