Care instructions
Oiled waxed canvas
Gently remove everyday dust with a dry cloth or soft brush.
If wet, wipe moisture away with a dry cloth and allow to dry naturally in a well-ventilated place.
Washing machines and strong detergents are not recommended because they may damage the waxed finish or the material's texture.
Use creates shades and scuffs on the surface; these are also part of the character of oiled waxed canvas.
Crazy Horse leather
A light wipe with a soft, dry cloth is usually sufficient.
If the leather becomes dry, use a small amount of cream or oil suitable for Crazy Horse leather.
Application may darken the colour, so always test on an inconspicuous area first.
Precautions for use
- This product uses oil-and-wax-treated canvas but is not fully waterproof.
- It is not designed for prolonged heavy rain, immersion or strong water pressure.
- Wipe away moisture promptly if wet.
- Natural cowhide may show creases, uneven colour, small marks and vein patterns.
- These are appearances found in natural leather. Contact us about any condition that concerns you.

Colour transfer: precautions and care
Due to the nature of Crazy Horse leather, colour may transfer during use or storage. Take particular care when it touches light-coloured clothing or fabrics. Please note the following.
- Check that care products suit the material: Test leather sprays and similar products on an inconspicuous area before use.
- Regular maintenance: Check that leather oils or creams are suitable for the material and test on a hidden area first. Care does not completely prevent colour transfer.
- Storage after use: After using the bag, store it in a well-ventilated place. Avoid direct sunlight, heat and high humidity.
Notes about product information
- Colour differences: The photos show the actual product, but colours may vary under different lighting or on different screens.
- Texture differences: Cowhide texture varies slightly between areas. Thickness and texture may differ depending on the part of the hide. Please bear this in mind.
- Natural characteristics: Natural leather has individual textures, marks, folds, spots and vein marks. These are among the appearances found in natural leather.
- Changes in smell: If the smell bothers you just after purchase, air the item in the shade in a well-ventilated place. The time needed for the smell to lessen varies between items.

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.
