What is the MD Notebook Bag?

It is a minimal vertical case for an A5 MD notebook. MD PRODUCT calls it a dedicated case that inherits the MD Notebook’s philosophy of ultimate simplicity. It holds only the minimum you need to write and record: an MD notebook, a pen and a smartphone.

What is it made of?

The same goat leather as the covers. The page says the leather is supple, resilient, lightweight and very durable, vegetable tanned and uncolored, so it keeps its natural color. As it is used and exposed to sunlight the color deepens and turns amber, and the case gains depth along with the stories you write.

How is it organized?

A phone pocket and pen slots. MD PRODUCT lists a sturdy pocket for a smartphone and multiple pens, in a simple design meant to be carried anywhere and suited to modern ways of working. It gives no inside dimensions, so check that your pen and phone fit before relying on it.

How does it compare with the covers?

It costs 550 yen more than the A5 goat leather cover and carries your phone. The A5 goat leather cover is 13,200 yen against 13,750 yen for the bag, and the cow leather cover is 16,500 yen. For a pen-only solution see the Midori MD system guide.

What should you check before buying?

Availability and fit. The page marked the bag Coming Soon on the day we read it, so it may not be orderable yet. It gives no inside dimensions, so check that your phone and pens fit before relying on it. The price is the Japanese store price with tax at 158 yen to the dollar, and shipping from Japan is extra. We have not handled the case.

Which MD notebooks does it fit?

The one that matches the size name. The A5 covers are named for the A5 MD Notebook, which is 176 pages of cream MD Paper at 80 g/m² according to our guide, and the family also has a cotton paper version. MD PRODUCT’s pages do not list inside dimensions or the notebook models each cover takes, so confirm with the store if you plan to use anything other than the standard notebook.

How does vegetable-tanned leather age?

It darkens and shows wear. This is general to the tanning method rather than a claim from the product page: untreated, vegetable-tanned leather tends to darken with sunlight, handling and the oils in your skin, and to pick up marks that many owners count as patina. MD PRODUCT says as much for its own covers, describing the color turning amber and the scratches as part of the character. Because the leather is uncolored, expect the color you receive to be paler than the color it ends up.

Where is it made, and what does it cost?

The page doesn’t say. At 13,750 yen with tax (about US$87.03) it is in our $$$$ band (over $75).
