What is the Zebra T-3?

It is Zebra’s mini ballpoint for planners: a slim stainless steel pen 100 mm long that fits in a pen loop or a planner’s spine. Zebra Japan files it under 手帳用, “for planners”, with the tagline “a short size that fits in your planner”.

In the US, Amazon.com sells it as the Zebra Mini Ballpoint Pen (T-3) and JetPens as the Zebra Techo T-3 Mini, with a metallic silver barrel and a black clip.

How small is the T-3 compared with a regular pen?

It is about a third shorter than a full-size Zebra F-701 and much thinner. At 100 mm it is shorter than an A6 page is wide (105 mm), so it can lie inside even a small planner.

What refill does the T-3 take?

Zebra’s 4C refill in 0.7 mm with black oil-based ink. Hunter Paper Co. calls it a D1 refill, the standard mini size that many multi-pens and mini pens share.

Zebra Japan sells the 4C-0.7 separately, so a T-3 can be refilled rather than thrown away.

How do you open and close it?

Press the top button to extend the point, then squeeze the clip to retract it, per Hunter Paper Co.

How does the T-3 compare with other pocket pens?

It is among the cheapest of the pocket pens we compare, mid-length, and at 5.6 mm much thinner than the 13 mm Kaweco Sport. The Kaweco Sport ballpoint is a little longer and much thicker, and the Fisher Bullet is shorter but needs its cap posted to write.

Pen Closed Refill Made in Band
Zebra T-3 100 mm (3.9 in) D1 (4C) Japan $$
Kaweco Classic Sport ballpoint 105 mm (4.1 in) D1 Germany $$$
Fisher Space Pen Bullet 96 mm (3.77 in) Fisher PR4 United States $$$
Rite in the Rain No. 92 86 mm (3.4 in) Pressurized cartridge United States $$

From our best pocket pens comparison. Because the T-3 and Kaweco Sport ballpoint share the D1 size, a favorite D1 refill can move between them. The capped Penco Bullet Ballpoint Pen Light also takes a 2.3 × 67 mm 4C refill, in an 8 g, 93 mm resin body.

The T-3 is the one to choose when width matters most, as in a planner spine or a narrow pen loop; for wet weather, a pressurized pen suits better.

How much does the T-3 cost?

In Japan, ¥440 (about US$2.80) with tax, per Zebra; in the US it sits in our $$ band, $5–20.

The matching TS-3 pencil also lists at ¥440 (about US$2.80) in Japan.

Yes: it is one of the best-known planner pens. The main Amazon.com listing had 3,732 ratings on October 23, 2026, and our pocket pens roundup picks it as the cheapest pocket pen.

For a bigger metal everyday pen, see the Fisher Space Pen AG7.

Where is the Zebra T-3 made?

In Japan, according to Hunter Paper Co.’s listing. Zebra’s Japanese product page doesn’t state a country. Zebra is a Tokyo company; our Zebra history covers its story.
