MD PRODUCT is the maker's current name for the Midori MD line from Designphil. Our [MD Notebook A5 guide](https://stationerytimes.com/guides/midori-md-notebook-a5/) covers the notebook it wraps, and the [MD system guide](https://stationerytimes.com/guides/midori-md-system-guide/) lists the other covers. ## How big is it, and what is it made of? **It opens to 216 × 315 mm, weighs about 31 g and is clear PVC.** The figures below come from MD PRODUCT's English product pages, which give the open size, pen holder and weight for each cover. | Cover | Open size (H × W) | Weight | Pen holder | Price | |---|---|---|---|---| | A7 | 113 × 168 mm | about 15 g | none listed | ¥352 (about US$2.20) | | A6 | 153 × 228 mm | about 14 g | 10 mm | ¥374 (about US$2.40) | | B6 Slim | 181 × 228 mm | about 17 g | 10 mm | ¥396 (about US$2.50) | | A5 | 216 × 315 mm | about 31 g | 10 mm | ¥440 (about US$2.80) | The A7 and A6 weights come as listed; the A6 is lighter than the A7 on MD PRODUCT's pages, and we couldn't tell why. The A5 cover's item code is 35661006. ![Side sketch of three layers: the outer clear PVC cover, a dashed glassine jacket and the cream MD Notebook inside](https://stationerytimes.com/images/md-notebook-cover-clear-a5-layers.svg?v=018f6503) *Our sketch of the layers; it is not to scale. Original illustration made for this guide. © Stationery Times.* ## Which MD notebooks does the A5 cover fit? **The A5 MD Notebook, Cotton, Thick, Diary and Diary Thin.** That is MD PRODUCT's list. Yoseka adds the A5 Journal Frame and Dot Grid. Two A5 notebooks take other covers. The 1 Day 1 Page A5 has its own cover that opens 11 mm wider, and the A5 Square has one too. The listing doesn't say whether the plain A5 cover will stretch over either, so use the matching one. ## Should the glassine jacket stay on? **Yes, according to MD PRODUCT.** It says to put the cover on with the glassine paper still wrapped around the notebook, because that softens the inorganic feel of the vinyl. The cover protects against dirt and, in MD PRODUCT's words, subtly against water. It doesn't claim a waterproof rating, and we haven't tested one. ## Which other sizes are there, and how do you pick one? **Choose the cover named for your notebook's size, because the open sizes are cut to fit.** MD PRODUCT's lineup runs A7, A6, B6 Slim, A5 Square, A5, A4 Variant and the A5 1 Day 1 Page. The A5 is the largest at 315 mm open of the four in the table above, and the 1 Day 1 Page cover is wider still at 326 mm. The 1 Day 1 Page cover is ¥550 (about US$3.50), which makes it the dearest we read. ## How does the pen holder work? **It is a loop with a 10 mm inner diameter on the A5, A6 and B6 Slim covers.** A pen barrel thicker than 10 mm won't go through it. MD notebooks suit fountain pens, as our [best notebooks for fountain pens](https://stationerytimes.com/guides/best-notebooks-for-fountain-pens/) roundup explains, so check your pen's barrel width first. The A7 listing shows no pen holder. ## Where is it made, and what does it cost in the US? **In Japan, according to MD PRODUCT.** Its English page for the A5 cover says Made in Japan, as do the A6, B6 Slim and A7 pages. MD PRODUCT's English store lists the A5 at ¥440 (about US$2.80). Yoseka Stationery, a US importer, listed it in our $$ band ($5–20) on October 30, 2026.
