MD Product Notebook Bag Vertical Goat Leather (A5)

The MD notebook bag made from vegetable-tanned goat leather is the minimalist carrying system for the MD notebook in A5 format. Crafted from a single piece of leather, the bag lies flat and supple in the hand – lightweight, yet surprisingly durable. The leather is undyed: initially cool and light beige, it develops a warm, caramel patina with light and use, making each piece unique.

Features

• Single-piece construction: The entire bag is cut from a single piece of goat leather. This means the MD notebook A5 fits perfectly without pressure marks – no seam ridge that could damage the notebook's surface.
• Vegetable-tanned, undyed leather: No color, no coating. Those who allow for ink, light exposure, and traces of use will experience how the leather transitions from light beige to a deep amber tone – a material that grows with your own writing story.
• Main compartment for MD notebook A5: Fits the MD notebook (A5) as well as the MD notebook Light (A5, up to 3 booklets). The MD Paper Pad in A5 format also fits.
• Front pocket for smartphone: The larger of the two outer compartments holds a smartphone – deep enough for common display sizes.
• Pen compartment for two writing instruments: The narrower front pocket holds two pens – fountain pens, fineliners, ballpoint pens. The opening is tight enough that pens won't slip out.
• Vertical format: The portrait orientation allows for a side grip that minimizes the feeling of inertia when switching between desk and on-the-go.

Application & Tips

• The undyed leather is deliberately without a protective layer – initial fingerprints and ink traces are normal and become less noticeable over time as the patina grows more evenly. Those who want to protect the leather initially can sparingly work in a colorless leather fat.
• For fountain pen enthusiasts: The pen compartment is ideal for two fountain pens or one fountain pen and one fineliner. Those who love writing with broad or flex nibs and have a second nib for corrections will find the perfect place here.
• The main compartment fits the MD notebook A5 snugly – cards, notes, or a folded sheet can be slipped between the notebook and leather without the bag puffing up.
• In everyday use, the bag works as a standalone minimal set: notebook, fountain pen, smartphone – that's all you need for an appointment, a train ride, or a workday in a café.
• The leather responds to sunlight: those who want an even patina can occasionally lay the bag flat in indirect sunlight. Those who prefer contrasts let wear marks develop unplanned.

For Leather Enthusiasts

The goat leather comes from vegetable tanning and is completely untreated – no pigment layer, no wax seal, no embossing. Vegetable-tanned leather reacts more strongly to moisture and light than chrome-tanned material, but develops a much more pronounced individual surface. Small scars, color variations, and slight irregularities in the initial state are features of genuine material and not quality defects. Those who travel with ink bottles or fountain pen cartridges should simply wait if ink contacts the leather: most stains soak into the patina rather than causing permanent damage.
