The same cover family houses the [A6 weekly vertical planner](https://stationerytimes.com/guides/marks-storageit-a6-weekly-vertical-planner/) and the landscape [A6 Desk notebook](https://stationerytimes.com/guides/marks-storageit-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. ![The A6 planner, A6 Desk notebook and A5 notebook binders drawn to scale side by side](https://stationerytimes.com/images/marks-storageit-sizes.svg?v=e84d2449) *The three storage.it binders at 1 mm = 1.1 px; sizes from retailer listings, pockets drawn by eye. Original illustration made for this guide. © Stationery Times.* ## 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](https://stationerytimes.com/guides/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 | | Pages | 224, dated Sep 2026 to Dec 2027 | 128, 5 mm dots | 128, dotted left and lined right | | Retailer price on Oct 31, 2026 | €19.50 (about US$22) | €13.90 (about US$16) | SEK 198 (about US$20) | | Refill | Not confirmed | Dotted insert, SEK 89 (about US$9) | Insert, SEK 89 (about US$9) | 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. ## Frequently asked questions ### Why is one page dotted and the other lined?
