Brass with an antique-like glow and aging.
Brass, which is resistant to corrosion and easy to process, is an alloy of copper and zinc.
Generally, it has been used for construction, shipbuilding, furniture, etc.
The most familiar one is that the "5-yen coin" with a hole is also made of brass.
Since the brass carabiner is in a pure state without surface treatment, the surface is oxidized by touching with air or human hands, and you can enjoy aging as you use it.
If you are concerned about surface oxidation, you can restore the original shine by polishing with a cloth containing abrasives or polish.
The appeal of brass is that you can enjoy aging and care according to your taste.
By using it for many years, a unique taste will come out, and by becoming familiar with your own lifestyle, you can use it with even more attachment.
Since the way it changes over time depends on the frequency of use and the environment, it will become your own unique product.
