Miquelrius LEATHER Notebook with Index — 104 x 150 mm, 300 Sheets, Black
104 x 150 mm (8º)300 sheets · 70 g/m²5 mm squared + indexRecycled leather cover
The Miquelrius LEATHER A042090 is a 104 x 150 mm pocket notebook with an index, 300 sheets of 70 g/m² white 5 mm squared paper and a flexible black cover in recycled leather, for people who keep contacts, client notes, logs or vocabulary lists that they need to find again quickly.
Miquelrius has made paper products in Barcelona since 1839. In its LEATHER range the covers are recycled leather — 75% leather fibres bound with 25% natural latex — which gives the feel of leather without a full-grain hide. The “8º con índice” format is the smallest in the range: a little larger than a postcard, with an index so entries can be filed by letter or topic.
How to choose in this range: the 104 x 150 mm size with index is for reference books you look things up in; the larger 152 x 210 mm (4º) versions without index suit journals and meeting notes. This model is the small indexed one, squared, in black.
What's in the Box
- 1 × Miquelrius LEATHER notebook, 104 x 150 mm, with index, 300 sheets, 5 mm squared, black cover
- No pen, bookmark or refill is included
What It Means in Practice
- 300 sheets is 600 pages — a reference book that lasts for years of contacts or log entries
- 104 x 150 mm fits a jacket pocket, a small bag or a glovebox
- The index lets you jump straight to a letter or section instead of paging through
- 70 g/m² paper keeps 300 sheets compact; use ballpoint, gel or pencil rather than wet inks
- The flexible cover bends with you in a pocket instead of digging in like a hard cover
What Will Not Work
- Not A5 or A4 — it is a small 104 x 150 mm pocket format
- Not lined — the pages are 5 mm squared
- Not refillable — it is a bound notebook, not a ring organiser
- Not genuine full-grain leather — the cover is recycled leather fibre with natural latex
- Not a diary or planner — no printed dates

Frequently Asked Questions
Is the cover real leather?
It is recycled leather: 75% leather fibres bound with 25% natural latex. It looks and feels like leather but is made from recovered material, not a single hide.
What is the index for?
It lets you file entries by letter or topic — useful as an address book, client log or vocabulary book.
Will a fountain pen work?
70 g/m² paper is thin to keep 300 sheets compact. Ballpoint, gel and pencil work well; very wet inks can show through — test on the last page.
Is there a bigger version?
The LEATHER range also has 152 x 210 mm (4º) notebooks with and without index. Ask us for the exact code you need.
Singular Expert Insight · Buyer's Guide
Most people buy a pocket notebook for writing and then lose things in it. The index on the A042090 solves that: it is a small reference book first and a notebook second, and 300 sheets means it rarely needs replacing. The recycled leather cover is soft and flexible, which suits a jacket pocket better than a hard cover. For larger notebooks and desk supplies, see
our stationery range.
✓ Buy it if you want a compact, long-lasting indexed notebook for contacts, client notes or logs.
✕ Skip it if you need A5/A4, lined paper, or a refillable organiser.
→ Also consider the Miquelrius A4 spiral notebooks in our range if you need a full-size notebook.
