A form about 6 cm deep, for choosing the tools you need
Its slim side profile invites you to choose what you will use today. Rather than leaving several days' tools inside, arrange the contents for your destination. A briefcase for those who like a bag to fit their own working routine.
Give belongings separate places with the small-item pockets and laptop divider; there is also an exterior pocket. Arranging items by size and frequency of use lets you see your preparations when you open the bag. The lining is polyester and the handle is soft.
A plain design draws attention to the leather
The material is crazy horse cowhide. Its plain design leaves an impression through the leather's shading and texture rather than decoration. Notice the parts you touch or bend during use, and enjoy finding a different expression from when it was new.
Beside your desk or carried in your hand, this is something you see daily, so liking its material matters. Growing fond of a bag chosen for work is one of the pleasures of living with familiar tools.
Arrange your documents and head for a conversation
Before a meeting, check what you want to communicate and gather the documents. Place pens and your phone in the interior pockets, close the zip and set off. Knowing where your prepared tools are lets you get ready in your own order at the destination.
With a jacket or just a shirt, add a slim outline and calm leather character to your usual work clothes. Rather than changing your appearance dramatically, reflect your taste in everyday belongings. That is a way of choosing a bag we hope you enjoy.
On days off, a tool for bringing thoughts together
Take out the work papers and prepare a notebook for your own studies. Whether attending a class or researching in a quiet place, changing the contents of a familiar bag lets you head out with the same routine on a day off.
When noting ideas and organising them one by one, it is pleasant to feel attached to the tools at hand. Choose a bag that suits your mood just as you choose a favourite pen. This briefcase can accompany time spent learning for yourself, not only working.
Come home and prepare the next day
At the end of the day, open the bag and remove papers and items that have served their purpose. Return what you will use tomorrow and glance at the leather's surface. Repeating these brief moments of care and preparation makes both the leather's changes and your preferred arrangement familiar.
For these everyday moments
- For those who want to select essential tools for a slim briefcase
- For those who want to use a laptop divider and small-item pockets
- For those who enjoy crazy horse leather in a plain design
Choose things you love for what you handle every day.
It need not be a major change: choosing one work tool anew can make morning preparations a little more enjoyable. Take Briefcase D to your next job or to learning for yourself. Why not welcome a bag that settles into everyday life?
Natural leather and care
Natural leather varies from piece to piece in texture across the hide, wrinkles, marks, colour shading and vein patterns. Lighting during photography and screen settings may make the colour look different from the actual item.
Friction, perspiration or moisture may cause colour transfer. Take particular care around light-coloured clothing and fabrics. Choose leather waterproofing sprays, oils or creams suitable for the material and test colour and texture changes in an inconspicuous area before use. Such care does not completely prevent colour transfer.
Store in a well-ventilated place away from direct sunlight, heat and high humidity. If the natural leather smell bothers you after purchase, allow it to air and observe the change. The time it takes to fade varies between items.

What Is Crazy Horse Leather?
Crazy horse leather is cowhide treated with oils and waxes to create a finish that changes in colour and surface character with use. Despite its name, it is not horse leather.
A finish that develops character
Bending or rubbing the surface can bring out lighter and darker areas. Areas that are handled frequently may develop a sheen, while creases and surface marks contribute to a patina over time. The way the finish changes depends on the item, how it is used and how it is cared for.
Natural leather also varies in grain, texture and colour. Product photographs show examples; lighting, screen settings and the individual piece of leather can affect its appearance.
How it differs from other materials
Check the material on each product page. A canvas bag with crazy horse leather details is not an all-leather bag. PU with a crazy horse-style appearance is synthetic leather, and needs different care from genuine cowhide.
Choosing a bag or wallet
Choose the shape, dimensions, weight and storage for what you plan to carry. Do not rely on a laptop’s screen size alone to judge fit; compare the device’s actual measurements and the thickness of any case. For a smaller accessory, check the length and thickness of the tools or items you want to store.
Moisture and colour transfer
The leather is not fully waterproof. Avoid heavy rain and prolonged wet conditions. Friction, perspiration and moisture can cause colour transfer, particularly onto light-coloured clothing and fabrics. A protective spray or conditioner cannot guarantee that colour transfer will stop.
Everyday care
- Wipe dust gently with a soft, dry cloth.
- If wet, blot away moisture and let the leather dry in the shade with good airflow.
- Avoid direct heat, sunlight and humid storage.
- Use care products suitable for the finish, following their instructions and testing on an inconspicuous area first. They may change the colour or texture.
- If a new item has a noticeable leather smell, let it air in a shaded, ventilated place. The time it takes to settle varies.
When to ask for help
Natural variation does not mean every problem is part of the material’s character. If you are concerned about damage, construction or another issue, contact cowmono with your order number and photographs.

Leather Colour Transfer and Care
Leather dyes and finishes can transfer onto clothing, furniture or other fabrics. Friction, moisture and perspiration can increase the risk. This can happen with new leather and does not always disappear after a fixed period of use.
Why colour transfer happens
Leather is a natural material, and finishes vary. Contact with damp fabric or repeated rubbing can move colour from the leather surface onto another material. Take particular care with light-coloured clothing, bag linings and furniture.
Taking care during use
Before first use, wipe the surface gently with a soft, dry cloth. Avoid prolonged contact with light-coloured fabrics, especially in wet or humid conditions. If the leather gets wet, blot moisture away and let it dry in the shade with airflow, away from heaters and direct sunlight.
Cleaning and storage
Choose care products suitable for the specific leather finish. Follow their instructions and test on an inconspicuous area first, since cleaners, oils, creams and sprays can change the colour or texture. Do not assume a care product will make the leather waterproof or prevent all colour transfer.
Store leather items in a dry, ventilated place away from direct sunlight, heat and humidity. Keep differently coloured leather and light fabrics from rubbing together during storage.
If you are concerned about a particular item, contact cowmono with your order number and photographs.
