Tombow Zoom 505 Metal Polish Black Review: An All-Black Water-Based Ballpoint That Gets the Details Right

Introduction

The Tombow Zoom 505 Metal in Polish Black is a water-based ballpoint that leans hard into one idea: a fully black, glossy, cigar-shaped pen that feels more premium than its stationery-aisle neighbors. Released in February 2019, this version adds brass parts to the established Zoom lineup, and that single change noticeably shifts both the look and the feel of the pen. After spending real writing time with it, the highlights are clear: a smooth, bold writing feel, excellent balance, and one of the nicest cap-posting experiences we have come across. There are also a couple of quirks worth knowing before you buy.

About Tombow

Tombow Pencil opened in 1913 as Ogawa Shunnosuke Shoten. In the Taisho era the company ran playful promotions, including pencils tied to American films and pencils bundled with small dolls. In 1928 it released Japan’s first drafting pencil, and in 1939 its operations were reorganized into two companies, Tombow Pencil Trading Co. and Tombow Pencil Manufacturing Co., setting the stage for steady expansion. The MONO eraser became a full product in 1969 after two years as a service item, and the Zoom series itself debuted in 1986. Today Tombow operates overseas bases and has spent more than half a century also developing cosmetics as an OEM manufacturer, a quietly unusual resume for a pencil company.

Zoom 505 Metal: Lineup and Price

The Zoom 505 lineup includes a mechanical pencil, an oil-based ballpoint, a water-based ballpoint, and a water-based ballpoint Havana. The Metal reviewed here is the water-based ballpoint, priced at 3,300 yen including tax. Color options are Hairline Silver, Hairline Black, and Polish Black, and the Polish Black variant is the one on the table here.

Design and Build

This is an all-black pen, from the barrel to the tip cone to the inside of the cap. The barrel is aluminum, and unlike the hairline-finished siblings, the Polish Black version gets a true polish, so the surface is glossy rather than brushed. The signature Zoom feature is a ring near the center of the barrel, and on this model that ring is made of brass instead of rubber, which changes the visual character and adds a sense of weight and substance.

The clip is thin and fairly stiff, and it grips pockets firmly. The knockout section (the part behind the grip) is rubber, while the cap is a friction-fit push-on type that closes with a satisfying two-stage feel. The grip is elastomer: no stickiness, a smooth dry texture, and it tapers slightly thinner toward the tip. The black tip cone keeps the color story consistent.

In hand it measures 138mm long, weighs 36g, with a maximum barrel diameter of 17mm. That is a thick, substantial pen with a low center of gravity.

Writing Performance

The included refill is the BKL5P33, a water-based pigment ink with a stainless steel 0.5mm tip. On paper, the line is smooth and easy, with a crisp, vivid black. The pigment ink dries quickly and the color depth is genuinely good. One observation: on cheap copy paper the tip can feel like it catches slightly and the ink can feather, and the line reads closer to a 0.7mm width.

Switch to a quality notebook and the story changes completely. The same refill glides without any catching, and the feathering disappears. Bleed-through testing drives the point home: on copy paper the ink sails straight through, while on a well-made notebook there is no bleed-through at all unless you press hard deliberately. The lesson is simple: this pen rewards decent paper.

Everyday Use: Balance, Grip, and Cap Posting

The balance is a strong point. A thick barrel combined with a low center of gravity and moderate weight means the pen puts down ink reliably even with light writing pressure, and long sessions do not tire the hand. The grip is comfortable, dry to the touch, resists dust buildup, and never slips.

The cap posts beautifully. Many capped pens post loosely, refuse to seat fully, or scuff the barrel in the process. The Zoom 505 posts with a satisfying, secure feel and a structure that protects the body from scratches; it feels almost like capping the pen normally. It is genuinely one of the most pleasant cap-posting experiences available, and it keeps the pen well balanced when posted, too.

Things to Consider Before Buying

Two quirks are worth flagging. First, the polished barrel shows fingerprints easily, which is an expected trade-off of the polish finish but will bother some people. Second, changing the refill produces a genuinely unpleasant sound, the kind that makes you wince. Neither is a dealbreaker, but both are worth knowing going in.

Buying Advice

Water-based ballpoints do limit where you can comfortably use them, but the writing feel here is something oil-based pens simply cannot deliver. Since the Zoom 505 Metal has been out for years, plenty of stationery fans already own one. If you have never tried it and you like an all-black, weighty capped pen, this is an easy recommendation, especially if you tend to write on decent paper where the refill shines.

Conclusion

The Zoom 505 Metal Polish Black nails the fundamentals: a striking all-black design elevated by its brass ring, smooth bold pigment ink, excellent low-center balance, and a cap-post mechanism that puts most other capped pens to shame. Add in a comfortable grip and quick-drying ink, and the only real complaints are fingerprints on the gloss and a cringe-worthy refill-change sound. For anyone drawn to a blacked-out pen that writes as good as it looks, it is a very attractive piece of stationery.
