MUJI USA lists 6 mm and 7 mm five-packs and a separate "Bleed Proof Lined" B5 five-pack at 6 mm, which averaged 4.6 stars from 22 reviews when we checked. Japan sells a matching "less show-through" (裏うつりしにくい) B5 pack at 7 mm. ![MUJI Planted Tree notebook 6 mm and 7 mm line spacing magnified four times](https://stationerytimes.com/images/muji-planted-tree-paper-notebook-rules.svg) *6 mm suits small handwriting; 7 mm leaves room for larger writing (1 mm = 4 px).* ## Is it good paper for pens? **MUJI USA says the sheets are thin but take highlighters and pens without bleeding through.** Reviewers on MUJI USA call the lines light and the paper bleed-proof, and MUJI Japan's B5 pack averaged 5 out of 5 from 79 reviews when we read it. We haven't tested it yet. A thin notebook paper like this usually shows some writing through the sheet with wet gel ink and fountain pens, so expect ghosting even where there's no bleed. ## How does it compare with other everyday notebooks? **It's thinner and cheaper per notebook than most Japanese school notebooks, with the colour-coded spines as its signature.** | | MUJI Planted Tree B5 | [MUJI Recycled Paper Notebook](https://stationerytimes.com/guides/muji-recycled-paper-notebook/) | [KOKUYO Campus](https://stationerytimes.com/guides/kokuyo-campus-notebook/) NO-3BN | |---|---|---|---| | Size | 252 × 179 mm | A6, A5 or B5 | 252 × 179 mm | | Sheets | 36 | 30 | 30 | | Rules | 6 or 7 mm | 6 mm (also grid, blank) | 6 mm | | Sold as | Five-pack | Single | Single and packs | | Spine | Cloth, five colours per pack | See guide | Laminated spine cloth | | Japan price | ¥299 (about US$1.90) for five | See guide | ¥210 (about US$1.30) each, before tax | MUJI figures are from MUJI's stores and Campus figures from KOKUYO Japan, as given in each guide. For handwriting at 6 mm, a fine pen such as the [MUJI gel ink pen](https://stationerytimes.com/guides/muji-gel-ink-pen/) at 0.38 or 0.5 mm keeps letters inside the lines. ## How big is B5 compared with US letter? **B5 is 179 mm (7 in) wide by 252 mm (9.9 in) tall here, about 1.5 in narrower and 1.1 in shorter than an 8.5 × 11 in letter sheet.** It still fits a standard backpack and gives a full-width writing line. Our [paper sizes guide](https://stationerytimes.com/guides/paper-sizes-explained/) compares B5, A5 and letter, and our [A5 vs B5 notebook size](https://stationerytimes.com/guides/a5-vs-b5-notebooks/) guide shows which suits class notes. ## Where is the MUJI Planted Tree notebook made? **MUJI lists Indonesia as the country of origin.** Both MUJI USA and MUJI Japan's store give Indonesia for the five-packs. MUJI is a Japanese brand run by Ryohin Keikaku in Tokyo. ## Frequently asked questions ### How many pages are in a MUJI Planted Tree notebook? Each notebook has 36 sheets, which is 72 pages, per MUJI USA and MUJI Japan. A five-pack gives you 180 sheets in all. ### What size is the MUJI B5 notebook in inches? MUJI USA lists it at about 9.9 × 7 × 0.2 in (25.2 × 17.9 × 0.4 cm). B5 is a little narrower and shorter than US letter paper, which is 8.5 × 11 in. ### What is planted tree paper? Paper made from fast-growing trees grown on plantations for the purpose. MUJI Japan describes it that way, and MUJI USA ties the line to its afforestation effort. ### Is the MUJI Planted Tree notebook bleed-proof? MUJI USA says the 6 mm notebooks are thin but take highlighters and pens without bleeding through, and it sells a separate Bleed Proof Lined B5 five-pack. We haven't tested either yet. ### What's the difference between the 6 mm and 7 mm MUJI notebooks? Only the line spacing. 6 mm fits more lines on a page and suits smaller handwriting; 7 mm is roomier. MUJI Japan sells both as B5 five-packs; MUJI USA lists 6 mm and 7 mm packs too. ### Are MUJI notebooks made in Japan? Not this one. MUJI USA and MUJI Japan both list Indonesia as the country of origin, although MUJI itself is a Japanese brand. ### How is this different from the MUJI Recycled Paper Notebook? The Recycled Paper Notebook uses recycled paper and has 30 sheets; the Planted Tree notebook uses plantation-grown pulp, has 36 sheets and comes in five-packs with coloured cloth spines. ## Sources - [【Ｂ５】植林木ペーパー ノート５冊組 ３６枚・６ｍｍ横罫・背クロス５色 (MUJI Japan online store, read in full: ¥299, 79 reviews averaging 5/5, origin Indonesia, paper from fast-growing planted trees, rules usable from any direction, spine cloth colours for sorting by use)](https://www.muji.com/jp/ja/store/cmdty/detail/4550584897320) - [MUJI Japan: 植林木 ノート search results (B5 6 mm and 7 mm, A5 and A6 6 mm five-packs, double-ring notebooks and loose leaf in the same paper)](https://www.muji.com/jp/ja/store/search/cmdty/%E6%A4%8D%E6%9E%97%E6%9C%A8%E3%80%80%E3%83%8E%E3%83%BC%E3%83%88?secid=all) - [MUJI USA: Planted Tree Paper Notebook - 6 mm (5 Pack) (25.2 × 17.9 × 0.4 cm, 36 sheets, 6 mm, Indonesia, best-seller tag)](https://www.muji.us/products/planted-tree-paper-notebook-6-mm-5-pack-nac10a5s) - [MUJI USA: Planted Tree Paper Bleed Proof Lined Notebook 6 mm - B5 (5 Pack) (22 reviews averaging 4.6, Indonesia)](https://www.muji.us/products/planted-tree-paper-bleed-proof-lined-notebook-6-mm-b5-5-pack-nac10a3a) - [MUJI USA: Planted Tree Paper Notebook - 7 mm (5 Pack)](https://www.muji.us/products/planted-tree-paper-notebook-7mm-5-pack-nac01a5s)
