For leather products, The metal fittings are just as important as the leather.
Hooks, zippers, belt buckles...these small parts not only support the functionality of leather products, but also greatly influence the look and feel of the leather products.

This time, we will introduce brass, which Munekawa chooses for the metal fittings in many of his creations.
What kind of material is brass?
Brass is an alloy made from copper and zinc, and is also known as yellow brass.
The 5 yen coin is probably the most familiar to us.

It has also been used around the world since ancient times for brass instruments, architectural decorations, and accessories.
The reason is that brass is a soft metal that is easy to work with and does not rust easily .
I experience this ease of handling of brass every day while making leather products.
Time polishes the unique look of brass
Munekawaが真鍮を選ぶ一番大きな理由は「雰囲気の良さ」です。
Brass is a highly corrosion-resistant material that does not easily rust. Therefore, just like leather, it is a metal material that you can enjoy changing over time.

When you first start using it, it will be a bright gold color, but as the surface oxidizes with exposure to air and hands, the shine will gradually fade.
Over time, the luster will fade and the color will deepen.
Brass that has aged over many years takes on a stately and warm appearance, like antique furniture. This is the charm of solid brass that cannot be achieved with plating.

Customers sometimes return products they have used for many years to the workshop for repairs.
Not only had the leather developed a beautiful amber color, but the brass fittings had also turned a beautiful antique gold, and even we on the production staff couldn't help but stare in awe.
How to deal with brass
We may also be asked for advice on caring for brass.
Here we will introduce how to care for brass.
Basically, just wiping it occasionally is enough.
There is no need to worry too much about daily maintenance. Basically, you can enjoy the natural aging process without doing anything.
If you are concerned about dirt or other stains, simply use a soft cloth to gently wipe away fingerprints and dirt from the surface while caring for the leather.
Care when verdigris occurs
Belts and other products worn in close contact with the body can develop a blue-green rust called verdigris if they are exposed to sweat or moisture for a long period of time. Verdigris is harmless if it comes into contact with the skin, but if it bothers you, you can remove it using the following method.

How to Remove Verdigris
Gently remove the patina with a cotton swab or scrap of cloth. Avoid scrubbing too hard as this may cause damage. A soft toothbrush is also recommended .
Care for radiance
If you want to bring out even more shine after the patina has worn off, follow the care steps below.
- Use a metal cloth or polishing compound to polish the surface of the metal fittings that have developed verdigris.
- Wipe thoroughly to ensure no cream or other residue remains.
Prevention methods
Once this problem occurs, it may recur, so regular maintenance is important.
- After use, wipe off any sweat or sebum with a soft cloth.
- When storing, keep in a well-ventilated, low-humidity place.
The verdigris forms a film on the surface and is said to have the effect of preventing internal corrosion. This is also one of the changes that are unique to brass, so leaving it as it is is also an option.
Additionally, the staff at Munekawa find the smoky color of aged brass to be appealing and tasteful, so we recommend using it as is.
