What is the KOKUYO C2 pen case?

The C2 is a slim, zippered polyester pen case from KOKUYO that opens wide into a tray. Instead of digging into a pouch, you unzip it and fold the walls out, and your pens lie in an open dish on the desk.

It’s made by KOKUYO Co., Ltd., the Japanese stationery company behind the Campus notebook and the Neo Critz pen case. KOKUYO’s Japanese site calls it a slim pen case that turns into a pen tray (ペントレーに早変わり), and US retailers such as JetPens sell it as the “C2 Tray Type Pencil Case”.

KOKUYO C2 specs

Sizes, prices, materials, colors and JAN codes come from KOKUYO’s Japanese product pages, which add that the width doesn’t include the handle and that, because the case is sewn, the dimensions can vary slightly. KOKUYO also says pen counts are only a guide that depends on the pens, so the counts and weights above are bungu.store’s.

To-scale side and end views of the KOKUYO C2 pen case L size F-VBF122: 200 mm (7.9 in) long and 50 by 50 mm in section — The C2 L size drawn to scale from KOKUYO's W200 × D50 × H50 mm. The S size is 5 mm smaller each way in section.

How does the C2 open into a tray?

You unzip it along its length and fold the walls outward, so the case lies open like a shallow dish. The Journal Shop describes the open tray as about 9 × 5 in.

That’s the case’s main appeal at a desk or in class: every pen is visible, and KOKUYO points out that small items like erasers and lead refills are easy to pick out. When you’re done, the walls fold back up and the zipper closes. KOKUYO adds that the zipper section works as a handle, so you can hang the case on the side of a desk, and the handle detaches with a snap button.

How many pens does the KOKUYO C2 hold?

bungu.store puts the L size at about 20 pens and the S at about 12, though counts vary with pen thickness. KOKUYO doesn’t give a count for the fabric cases and says any count is only a guide.

The Journal Shop’s own listing is inconsistent: its description says 20 or more pens, while its spec list says 10. A clip-on gel pen like the Zebra Sarasa Clip takes more room than a slim pencil, so expect the lower end with chunky pens.

Which colors and versions are there?

KOKUYO’s Japanese site lists the L size in Ash Black (F-VBF122-7) and Violet Blue (F-VBF122-8), and the S size in those two plus Pale Turquoise (F-VBF140-9). The color code is the number after the model.

Older colors still turn up at retailers: The Journal Shop lists Khaki Yellow (FVBF122-3) and S-size Pink, Green, Light Blue and Purple, and an ended eBay listing shows Navy × Blue (F-VBF122-1).

KOKUYO also makes a clear version of the C2 (F-VBF143 series), listed at 50 × 50 × 202 mm with a PVC body, about 20 pens and a list price of ¥980 (about US$6.20) before tax. For a slim case in wipe-clean PVC with a different shape, see the DELFONICS Quitterie.

How does the C2 compare to the Neo Critz and LIHIT LAB Teffa?

The C2 is the slimmest of the three and the only tray-type; the Neo Critz stands up and the Teffa opens like a book.

	KOKUYO C2 (L)	KOKUYO Neo Critz (Regular)	LIHIT LAB Teffa
Size	200 × 50 × 50 mm	85 × 50 × 195 mm	200 × 50 × 120 mm
On the desk	Opens into a tray	Folds into a pen stand	Opens flat like a book
Capacity	About 20 pens	About 12–15 pens	About 12–14 pens

Neo Critz figures come from KOKUYO and retailers, and Teffa figures from LIHIT LAB. Pick the C2 if you want something slim that still shows every pen at a glance. If you carry just three good pens and a pocket notebook, the Sinclair Model R is built for that instead.

Where is the KOKUYO C2 made?

KOKUYO’s global online store gives China as the country of origin for the S size (F-VBF140); we found no source that states it for the L size.

KOKUYO’s Japanese product pages don’t list the country. An eBay listing we relied on earlier gave Japan for the Ash Black L, but it is no longer available, so we have dropped that claim. Check the label on the one you buy.
