Our take on the Tarnish Resistant 304 Stainless Steel Ear Nuts, Butterfly Earring Backs for Post Earrings

These are butterfly earring backs made of 304 stainless steel, the same alloy used in many watch cases and kitchen gear. Each back measures about 9.5mm wide and long and 4mm thick, with a 1mm hole that fits standard post earrings. The steel is sold as tarnish resistant, so the backs hold their silver tone longer than plated brass findings, which darken and flake with wear. They suit anyone replacing lost backs or keeping a stash for studs that slip off.

Pros
  • 304 stainless steel resists tarnish and rust better than plated brass
  • Butterfly shape grips standard posts and is easy to pinch on and off
  • 1mm hole fits common post diameters
  • Steel color stays consistent, so mixed batches look alike
  • Sturdy 4mm thickness holds its shape through repeated use
Cons
  • Not hypoallergenic surgical steel, so highly nickel-sensitive ears may still react
  • 1mm hole is too small for thicker posts
  • Plain steel look does not match gold or rose-gold jewelry
  • Butterfly backs can loosen over time with heavy daily wear

Questions and answers

Will these fit standard stud earrings?
The hole is about 1mm, which fits most standard post earrings. Posts thicker than that will not pass through.
Are they really tarnish resistant?
304 stainless steel resists tarnish and rust far better than plated brass. It can still dull over years of wear, but it will not flake like plating.
Are they good for sensitive ears?
304 steel contains nickel, so it is not the same as hypoallergenic surgical steel. Most people are fine with it, but very nickel-sensitive ears may react.
How big are they?
Each back is about 9.5mm wide, 9.5mm long and 4mm thick. That is a standard butterfly size, not a large or locking back.
Do they match gold earrings?
No. They come in a steel color, so they suit silver, steel and white-gold tones rather than yellow or rose gold.
Can I use them on threaded or screw-back posts?
They are made for plain posts. Threaded posts and screw-back earrings need their own matching backs.
