What is the LIHIT LAB Teffa Book Style Pen Case?
It’s a zippered pen case from LIHIT LAB, a Japanese stationery maker, that opens flat like a book so every pen is visible at once. The model number is A-7551 (often written A7551), followed by a color code. It was sold for years in the US as the Teffa Pen Case - Book Style, and JetPens now lists it as the Book Style Pen Case - Standard. In Japan, LIHIT LAB sells it as ペンケース［ブックタイプ］ (“pen case, book type”).
LIHIT LAB, Inc. is a Japanese office-supply maker based in Osaka; its company profile gives May 1938 as its founding.
How does the book-style opening work?
A double zipper runs around the case, so it opens along its spine and lies flat like a book. LIHIT LAB’s catalog sums up the idea: because it opens like a book (見開き式), the pen you want is easy to find.
LIHIT LAB lists what’s inside and out:
- Pen straps: elastic loops that hold pens and pencils in rows; Tools and Toys notes they suit clip pens best.
- Three small mesh pockets: for erasers, lead refills and other small items.
- One large mesh pocket: big enough for scissors or a glue stick.
- Outside pocket: for cards and A7 (74 × 105 mm) memo pads.
LIHIT LAB adds that the lining is brown on colors 4 to 24 and gray on colors 103 to 135.

All figures are from LIHIT LAB’s Japanese catalog and online store; Japanshop.nl gives the same 120 × 200 × 50 mm. Some US listings have given 20.0 × 12.5 × 4.5 cm and a much higher pen count; we use LIHIT LAB’s figures. LIHIT LAB doesn’t publish a weight.
How much does it hold?
LIHIT LAB rates it at about 12 to 14 pens, and says the count depends on pen thickness. Reviewers have squeezed in more: in a 2011 review, The Pen Addict fit 17 pens plus a flash drive, a small stylus and a small sketchbook, and fit a Rhodia No. 12 pad in the back mesh pocket.
The outside pocket takes cards and A7 memo pads (74 × 105 mm), so a small notebook can ride along.
What is it made of, and is it water-repellent?
LIHIT LAB lists the body as polyester; we found no LIHIT LAB claim that the A-7551 is water-repellent or waterproof. The Pen Addict describes the fabric as shiny, easy to wipe clean and resistant to marks, and calls it nylon, which doesn’t match LIHIT LAB’s “polyester”. Treat it as wipe-clean, not waterproof.
One older complaint to know about: in 2016 The Gentleman Stationer reported a strong chemical smell from a Teffa case and didn’t recommend it, though several readers commented that theirs had no smell. We haven’t checked current production.
What colors does it come in?
LIHIT LAB’s online store lists 13 color codes for the A7551, including limited camouflage prints.
| Color | Model number |
|---|---|
| Orange | A7551-4 |
| Yellow green | A7551-6 |
| Brown | A7551-9 |
| Navy (藍) | A7551-11N |
| Black | A7551-24 |
| Coral | A7551-103 |
| Blue | A7551-108 |
| Jet black | A7551-124 |
| Camouflage: green, navy, maroon, black, ice gray | A7551-131 to A7551-135 |
LIHIT LAB’s catalog marks the camouflage prints as limited production. Yodobashi in Japan labels A7551-124 (jet black) as an overseas edition (海外版), so availability varies by market.
Which book-type size should you choose?
The A-7551 is the standard, single-layer book case; LIHIT LAB also makes thicker Double and Triple versions.
| Case | Model | Size (LIHIT LAB) | Pen capacity (LIHIT LAB) | List price (before tax) |
|---|---|---|---|---|
| Book type (Teffa / Standard) | A-7551 | 200 × 50 × 120 mm | About 12–14 | ¥1,350 (about US$8.50) |
| Book type Double | A-7555 | 200 × 70 × 120 mm | About 25 | ¥1,700 (about US$11) |
| Book type Triple | A-7556 | 200 × 90 × 120 mm | About 40 | ¥1,900 (about US$12) |
| Smart Fit double pen case S | A-7660 | 175 × 45 × 85 mm | About 10 | ¥1,500 (about US$9.50) |
Smart Fit is a separate LIHIT LAB line; the A-7660 is included for size only.
How does it compare to EASTHILL and KOKUYO Neo Critz cases?
Choose the LIHIT LAB book style if you want every pen laid out flat and visible; the other two are built differently. The EASTHILL pencil case is a zip pouch, and the KOKUYO Neo Critz is a pouch designed to stand up as a pen holder on a desk. See each guide for their sizes and capacities.
Pens worth carrying in it include the Pilot G2, Pentel EnerGel and uni-ball ZENTO Signature. The outside pocket is sized for A7 memos (74 × 105 mm), so a mini composition book at 83 × 114 mm may be too big for it.
Where is it made?
None of the LIHIT LAB pages or retailer listings we read state a country of origin for the A-7551. LIHIT LAB is a Japanese company, but brand nationality isn’t the same as where a product is made: one reader commenting on The Gentleman Stationer’s 2016 review said the tag on their Teffa case read Cambodia. Check the sewn-in label or packaging of your case.
