All four are made in Indonesia, per MUJI USA. MUJI USA gives no paper weight, ring diameter or cover material, so we can’t say how it takes fountain pen ink.
It suits people who want a cheap, plain notebook that folds back on itself.
Journaling and planning: 48 sheets (96 pages) ruled at 6 or 7 mm, a format MUJI tags for bullet journaling and note-taking.
Everyday carry: the A7 is about 105 mm tall and the A6 148 mm, small enough for a jacket pocket or small bag.
Skip it if you need to know the paper’s weight or ink resistance: MUJI USA doesn’t give them.
Which MUJI double ring notebook size should you choose?
Choose A5 or B5 for notes at a desk and the A7 or A6 for a pocket. A5 is 21 × 14.8 cm, the size many planners and notebooks use; our notebook sizes chart compares them with US sizes. The B5 gives about 4 cm more height and 3 cm more width.
The larger two sizes have 7 mm lines, which suit normal handwriting; the 6 mm of the A7 and A6 suits smaller writing. All four sizes cost under US$3 each when we read MUJI USA’s page on November 1, 2026, and prices change.
How does it compare with MUJI’s stitched notebooks?
The ring notebook folds flat and has more sheets; MUJI’s stitched notebooks are slimmer.
For the pocket-size ring notebooks, see the A6 with strap and the plain wirebound A6. The ring notebook is the one for writing while holding the book in one hand, since the cover folds behind the pages.
Where is the MUJI double ring notebook made?
In Indonesia: MUJI USA gives it as the country or region of origin for all four sizes. MUJI itself is a Japanese brand.
How much does the MUJI double ring notebook cost?
All four sizes are in our $ band, under $5. Each size costs more than the one before it, from the A7 to the B5. MUJI USA sells the notebooks as Final Sale, with no refunds or exchanges.
