Stainless steel earring posts are a great choice for making earrings because stainless steel is both sturdy and resistant to corrosion. Stainless steel posts with flat pads are ready for you to glue handmade embellishments onto them. Plated steel "fingernail" posts (sometimes called French clips) have a large gluing surface, and include a hinged back to hold the post in place, thus eliminating the need for earring backs. Additional styles of stainless steel earring posts include posts with a cup and peg, posts with loop, and earring findings with skull settings and rivoli crystal settings.
Please note that some people are allergic to the nickel that is commonly alloyed in stainless steels to give them strength and resistance to corrosion. (more info about hypoallergic metals)
