What is the MARK’S storage.it A5 notebook?
It is MARK’S Inc.’s A5 notebook in a clear PVC binder with a zip pocket. MARK’S says the range started in 2005; its brand page lists a Good Design Award in 2010. The same cover family houses the A6 weekly vertical planner and the landscape A6 Desk notebook.
How big is it?
The binder is 16.5 × 21.7 cm and the insert 14.8 × 21 cm. Both are Tidformera’s figures, and the insert matches A5.
What is on the pages?
Dots on the left, lines on the right, in every spread. The dots are 5 mm apart; the lines are 6 mm apart with support dots so a page can be split into three columns.
That suits layouts on one side and to-do lists and notes on the other. The paper is FSC-certified; Tidformera calls it thin and smooth and gives no gsm. See our best notebooks for bullet journaling for alternatives.
How does the pocket work?
A large plastic zip pocket on the outside, small pockets inside. Tidformera says it holds a pen, business cards, receipts, a small ruler or stickers, and warns that ink can transfer to the plastic. The binder is 90% recycled PVC per Tidformera.
Can you refill it?
Yes, with a separate A5 insert. Keep the binder and buy the refill, which has the same dotted/lined layout, 128 pages. Tidformera listed it at SEK 89 (about US$9) on October 31, 2026.
What colors and price?
Eight colors: Black, Blue, Craft, Mint, Navy, Pink, Purple and White. We have not sampled them, so we show no swatches. Tidformera listed the notebook at SEK 198 (about US$20) on October 31, 2026, at the top of our $$ band ($5–20).
How does it compare with the other storage.it formats?
It is the largest of the three and the only one with a lined side. The table uses the retailer figures above.
| A6 weekly vertical planner | A6 Desk notebook | A5 notebook | |
|---|---|---|---|
| Orientation | Portrait | Landscape | Portrait |
| Outside size | 4.5 × 6.0 in (about 114 × 152 mm) | 107 × 165 × 8 mm | 16.5 × 21.7 cm |

Pick the A5 if you want room for lists beside layouts and can carry a larger binder. The pocket here is big enough that Tidformera says it can carry pens, rulers or stencils.
Who is the zip pocket for?
Anyone who carries loose paper with the notebook. Tidformera lists business cards, post-it notes, receipts and stickers, and its tips page shows a calendar stencil and stickers kept in the cover. Its warning is the main trade-off: ink can stick to the plastic, so keep wet-ink pages and glossy stickers away from it. That is Tidformera’s advice, not ours from testing.
What do the retailer pages not say?
No gsm, no durability data and no MARK’S statement on this item. We read retailer pages and MARK’S brand page only, and haven’t tested it hands-on.
What country is it made in?
Tidformera says Japan. MARK’S pages we could read don’t name a country, so the origin is a retailer statement.
