Polished Brass delivers a bright, reflective finish with a distinctive glow. Over time, this finish develops subtle variations in tone, adding depth and character to interiors. Polished brass door levers pair naturally with neutral palettes, textured materials, and traditionally inspired spaces.

The finish is created by polishing raw forged brass to a mirror-like surface, then applying a clear gloss lacquer for protection.

Care: Clean regularly with a soft damp cloth and keep dry.

Caution: Take care not to damage the lacquer layer. Polished Brass is not recommended for coastal environments, where salt exposure may lead to tarnishing.
