What is the MD Notebook Goat Leather Cover?

It is the leather jacket for an MD Notebook. Midori’s MD PRODUCT store describes a durable, high-quality cover that grows with time. The goat leather comes from the mountains of Central Asia and is vegetable tanned, with a natural, uncolored finish that preserves the leather’s own color. The inside is not lined or colored.

What does the leather do over time?

It turns amber. MD PRODUCT says that as the stories in the notebook deepen, the cover changes color to amber, and that the unique scratches and unevenness on the back of the leather are part of its character. That is a claim about natural leather, not a promise of a specific shade.

Which size and price should you pick?

Match the notebook, then check the stock. MD PRODUCT lists six sizes, and these prices with tax:

Size	Price	About US$
A7	6,930 yen	43.86
A6	9,570 yen	60.57
B6 Slim	10,120 yen	64.05
A5	13,200 yen	83.54
A4 Variant	18,700 yen	118.35

The A7, B6 Slim and A4 Variant were marked Coming Soon on the day we read them. We did not find a price for the A5 Square goat cover. The clear A5 cover is the budget alternative.

How does it compare with the other covers?

It is the middle of the leather range. The cow leather cover costs 16,500 yen and is stated as made in Tokyo, and the vertical goat leather bag adds pockets. For the whole system see the MD system guide.

What should you check before buying?

Stock, size and the notebook it fits. The A7, B6 Slim and A4 Variant covers were marked Coming Soon, so they may not be orderable yet. MD PRODUCT’s pages gave no inside dimensions, weights or thickness, so match the size name to your notebook rather than to a measurement. Prices are Japanese store prices with tax at 158 yen to the dollar, and shipping from Japan is extra. We have not handled the leather, so we cannot report on smell, stiffness or break-in time.

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 state it. The leather is from Central Asia, and Midori’s Japanese MD PRODUCT store says nothing of manufacture for this cover. The A5 at 13,200 yen with tax (about US$83.54) is in our $$$$ band (over $75), while the A7 and A6 fall in $$$.
