Brand new in package with original packaging. Please note that the bag holding these have holes and scuffs from the earring backs. Please note the posts may have a slight bend in it from these being shipped without foam to protect them. I will be using foam when I ship these to protect them further as pictured. The backers are gold cylinders and have oxidized very slightly, blending in with the reverse side but can be seen in pictures. Smoke free home. For the composition and more please see the manufacturer’s website/contact the manufacturer. I only have the data from the packaging pictured. Due to variations in monitor color reproduction actual product coloring may appear slightly different than pictured
