Multi Blue Color  Stain Galss Coffin Pendant Stainless Steel Snake Chain .  
 
The Pendant measures  2 1/4" tall X  1 1/4" wide. 
The stainless steel chain is 20" long
 
NOTE : Coffins are made with lead free solder, which is a mix of 99.3/7 tin/copper.
I can not claim it to be nickle free. Some tin contain nickle has nickle in it as does mostcustom jewelry. 
Therefore some people may experiancean allergic reaction to the nickle. 
The solder cleans well with magic eraser and water.
