This wallet chain uses a brass chain. Brass is made of solid metal that has not been treated from the top to prevent discoloration. As you use it, it oxidizes and darkens, and the parts that rub against denim are polished. It glows dullly. It has a hook on one side and a lever nascan on the other. The hook is a hook-type hook that can be hung on a belt. This allows you to move the chain position to a good position. The hook is attached to the belt loop, and the end nascan is a wallet drop handle Please attach it to the It has a simple and timeless design without daring to add various parts. Normally, I think there are many manufacturers that do not have a header (mount) on wallet chains. It comes with a CALIFORNIA TOOLS mount, so it stands out when displayed. *All parts are solid brass. *Please note that the chain has dark spots due to its nature. Handling of brass products About brass and aging Products made of solid brass wood change color over time (over time). Please understand it as a characteristic of the material. Aging does not always occur uniformly throughout the product, and may be uneven at first. It will take some time to get used to the whole, so please enjoy the process. In places where it rains or splashes, there may be a pattern of raindrops on the surface. If you want to slow down the speed of aging, you can apply beeswax wax regularly. It has a glossy feel and can be kept in the condition it was delivered to some extent. *There may be changes over time before delivery. Please note that this is a characteristic of the material. *The method and speed of change vary depending on the installation environment. *Strong changes may occur in areas that may be subject to salt damage. How to care If dust or dirt is a concern, wipe it dry with a soft, dry cloth. If the dirt is strong, you can wipe it with water, but be sure to wipe it dry at the end. If patina (a type of blue-green rust) is bothersome and bothersome, gently polish it with a brass polishing cloth. Please refrain from wiping with chemicals as this may cause uneven wiping. If rain or hand marks turn black, the blackened area is not dirt, but a scientific change, so it cannot be wiped off. These marks overlap to create an antique texture. As time goes by and the overall color changes to a deep hue, I think the marks will not be very noticeable, so please keep an eye on them for a while. If you are concerned about the changed color or the pattern caused by water splashes, so if you want to restore it to a beautiful state, use a metal polish such as Picard Yes, but the texture will be different from the texture at the time of delivery, so please understand before using it.
