Keep it dry
Perfume, sweat and water dull the oxidised finish. Wear it last, take it off first.
Keep it black
Oxidised brass is blackened on purpose — it is meant to darken and deepen, not stay shiny like plated gold. A little care keeps the black in the detail and the highlights bright.

Keep each piece in the pouch it arrived in, away from air and other metal.
A dry cotton cloth after each wear is all it needs. Never use liquid or chemical cleaners.
