doesn't matter if you take them off while you shower, sleep, or work out, these cheap and horrible chains will tarnish. a complete waste of money

Had two of the Cain's come in looking great. Good coloring to them. The rest of the chains were covered in black gunk. Very thin. We tried to clean them off and ended up br asking 3 chains in the process. I will not buy again. Feels like I threw my money out the window.
