What is the TRAVELER’S COMPANY Brass Ruler?

It’s a 16 cm ruler cut from solid brass, with a 15 cm scale and one edge bent up so it stands off the page. It belongs to TRAVELER’S COMPANY’s BRASS PRODUCTS line of clips, pens and bookmarks made to go with the TRAVELER’S notebook.

TRAVELER’S COMPANY says the ruler is punched out of a brass plate with 45 tons of force, finished, bent, finished again and laser-engraved with its scale, and that such a simple tool demands delicate Made-in-Japan craftsmanship. TRAVELER’S COMPANY USA says the BRASS PRODUCTS line joined the notebook in 2010.

TRAVELER’S COMPANY’s Japanese product page gives the ruler as H20 × W160 mm, the package (a PP bag) as 105 × 200 × 3 mm and the origin as MADE IN JAPAN, but no weight. Manufactum gives the same 16 × 2 cm and adds 27 g and the 1 mm thickness; Milligram lists 15.8 cm.

Why is one edge raised?

The edge opposite the scale is bent up, so the ruler is easy to pick up and the ruling edge stays off the paper. TRAVELER’S COMPANY says it raised one side slightly so lines are easy to draw even with ink pens, and Manufactum says the angled side stands above the paper for ink or fountain pens.

That matters most with wet pens. A Pilot Kakuno fountain pen or a felt-tip fineliner can bleed under a flat acrylic ruler, while the raised brass edge keeps the line clean.

How big is it next to a notebook?

At 160 mm, it’s shorter than a TRAVELER’S notebook Regular refill (210 mm tall) and an A5 page, so it rides inside the notebook. It’s longer than the 110 mm page width, so on a Regular refill it measures down the page, not across it.

To-scale drawing: the 160 by 20 mm Brass Ruler and the 140.5 by 34 mm Midori Clip Ruler on a 210 by 110 mm TRAVELER'S notebook Regular refill page — The Brass Ruler covers about three quarters of a Regular refill's height.

Does it have an inch scale?

No: the engraved scale is in centimeters and millimeters only, from 0 to 15 cm (about 5.9 in). That suits metric dot-grid and grid notebooks, where 5 mm squares line up with the millimeter ticks.

If you measure in inches, pair it with an inch ruler. A clear acrylic ruler also lets you see the grid underneath, which brass can’t.

What else is in the BRASS line?

The ruler is one of several brass accessories from TRAVELER’S COMPANY, including template bookmarks with number and alphabet stencils. Paperwhisper sells the Brass Template Bookmarks alongside the ruler, and the maker describes the whole line as solid brass that ages with use.

How does the brass age?

It starts with a gold shine and darkens to a deep, dull tone with handling. TRAVELER’S COMPANY says the surface oxidizes with use, giving the ruler the look of an antique tool, and presents that change as the point of its brass line.

TRAVELER’S COMPANY USA has written about enjoying that aging on its leather covers and brass pieces together.

How does it compare with other rulers?

Choose it for ink and for carrying; choose a longer or inch-marked ruler for full-page or US measurements.

	Brass Ruler	Midori Clip Ruler	Westcott acrylic ruler
Length	160 mm (15 cm scale)	140.5 mm (10 cm scale)	12 in
Material	1 mm solid brass	0.3 mm brass, copper or steel	Clear acrylic
Extra	Raised edge for ink	Page clip and stencil	Inch and cm scales

The Midori Clip Ruler comes from the same parent company and doubles as a bookmark; the Westcott acrylic ruler covers a full A4 or letter page.

Where is the TRAVELER’S COMPANY Brass Ruler made?

TRAVELER’S COMPANY’s own Japanese product page says MADE IN JAPAN, next to the item number No.42167006. Manufactum also lists it as made in Japan.

In Japan, TRAVELER’S COMPANY raised the ruler’s list price from ¥1,650 (about US$10) to ¥1,980 (about US$13) including tax on October 1, 2025. Its product page notes that it doesn’t ship overseas to individual customers.

TRAVELER’S COMPANY USA says the brand was called MIDORI until 2015, so older listings sell the same ruler under that name. The BRASS PRODUCTS line dates from 2010, but we didn’t find a release date for the ruler itself.

Does the brass ruler fit in a TRAVELER'S notebook?

It's shorter than a Regular-size refill page (210 mm tall), so it lies on the page and can be carried inside the cover. It's longer than the 110 mm page width, so it won't lie flat across the page.

Is the TRAVELER'S COMPANY Brass Ruler the same as the Midori brass ruler?

Yes. TRAVELER'S COMPANY USA says the brand name changed from MIDORI to TRAVELER'S COMPANY in 2015, so older listings sell the same 42167-006 ruler under the Midori name.

Centimeters and millimeters only, up to 15 cm. There's no inch scale, so US users who need inches will want a second ruler.
