Please read descriptions for metal and size information & Jewelry Care page on www.thebeautycloset.us
Surgical Steel is the most common type of metal used with body jewelry and it is durable, safe and will not tarnish with proper care. This does contain some nickel so it is not a good choice for those with sensitive skin.
Titanium is the go to for those with sensitive skin because it does not contain any nickel.
Brass is also durable and safe but can tarnish if not taken care of.
If you have sensitive skin, please be cautious when purchasing & ensure you are checking with a piercer to discuss which metals are okay for you.
Also, please make sure you are self cleansing your body jewelry, initiating proper care & doing your own research on metals & gauge sizes.
