brass keyhole covers

Brass is an alloy consisting predominantly of zinc and copper. Brass is significantly more yellow than pure copper and bronze. It is a material that has always been appreciated for its resistance and its colour close to that of gold.
Brass resists moisture and does not rust, and is easy to maintain. Over time, the glossy surface will tend to oxidize naturally and become verdigris (greyish-green). This is a natural process of brass ageing and does not constitute grounds for complaint or is something covered by the warranty.
