The Tombow Zoom 707 is nothing if not distinctive. Between the accordion-like twist, the red ball at the end of the clip, and the protruding grip, it looks like no pen I’ve seen. In fact, it seems almost like a novelty pen.

That’s not to disparage it; the Zoom 707 is clearly a high-quality pen. It has a durable, metal barrel, a clip that secures snugly, and a twist mechanism that ejects the pen’s tip smoothly. It has a soft, rubber grip and comes with a ballpoint refill that’s comparatively darker and smoother than most (though some ink blobbing does occur).

Due to its size, however, the Zoom 707 is the kind of pen that’s best slipped inside a planner or pocket-notebook. Despite the grip section, which is noticeably thicker than the pen’s barrel, the Zoom 707’s slenderness is simply impractical for writing longer notes or letters. Writing at any length quickly becomes uncomfortable.

The Zoom 707 will likely run you anywhere from 15 to 35 dollars, depending on which color you’re after, and, to me, that seems a bit pricey given its limited practicality. If you’re in the market for a super-slim pen, I’d recommend checking out the Pilot Couleur. If you just want a unique-looking Tombow pen, I’d suggest the Airpress. The Zoom 707 is a nice pen, but it’s hard to beat these alternatives, as they typically run in the 5 to 10 dollar range.
