Each blank is one of a kind   
Raw brass jewelry component to create your design set jewelry, 
Patina is on both sides of the blank.
Metal - raw brass
Size - 36x30 mm / 1.4"x1.2"
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 no harsh chemicals are used.  
The brass/copper charms are covered by a thin lacquer layer to save the patina's natural color.
