The item is one of a kind, with unique patina colors and textures. 
The color of the patina may be different.
Patina is on both sides of the blank.
Metal - raw copper
Size - 6x4.5 cm / 2.2"x1.7"
Quantity - 1 large hammered rectangular cuff bracelet, bracelet blank (air chasing)
I made the photo on my workbench on my mobile phone. So, you can see the real colors of the patina!
The colors of the patina are natural, all processes are no harsh chemicals used.  
A thin layer of lacquer covers the brass/copper blanks to save the natural color of the patina. 
You can add additional layers of lacquer to protect the finish further.
