Over time, brass will naturally oxidize. This means its surface may deepen in color, develop a soft patina, or darken slightly depending on climate, humidity, and individual skin chemistry. Some pieces stay bright for years. Others shift more quickly. Both are completely normal.

Oxidation is not damage. It is a natural reaction between the metal and the world around it.

Many people love the aged character that develops. Others prefer to maintain the original golden brightness. Both expressions are beautiful.

Caring for brass is simple and requires only occasional attention.

To maintain its original tone:

• Store your piece in a dry place when not in use.
• Avoid prolonged contact with water, perfumes, lotions, and chemical products.
• After wearing, gently wipe with a soft cloth.

To restore brightness: Gently rub the piece with fresh lemon to naturally lift oxidation from the surface. Follow with a mild hand soap wash to remove any residue, then rinse carefully and dry thoroughly with a soft cloth.

The lemon acts as a natural brightener. The soap refines the finish. Thorough drying prevents future moisture marks.

Each KANTU piece is sealed with a clear protective coating to help preserve its golden tone and slow oxidation. However, as with all coated brass jewelry, this layer will gradually wear over time — especially in areas of frequent contact.

This is part of the material's nature. With proper care, your piece can remain luminous for many years.
