Our take on the Plastic Ear Nuts, Earring Backs, Clear, 3x4mm, Hole: 0.4mm

These are clear plastic ear nuts, the small friction backs that hold stud earrings in place. The 0.4mm hole fits standard thin earring posts, and the 3x4mm body is compact enough to sit unnoticed behind the earlobe. They suit anyone replacing lost backs or keeping a bulk supply for a jewelry box or small craft business. Compared with metal butterfly backs, plastic is lighter and gentler on sensitive skin, but it grips less firmly and wears out faster, so it is a consumable rather than a long-term fitting.

Questions and answers

Will these fit my earrings?
They fit posts up to about 0.4mm thick, which covers most standard stud earrings. Thicker or threaded posts will not pass through.
Are they good for sensitive ears?
They are plastic rather than metal, so they avoid nickel and other metal contact on the back of the lobe. The earring post itself still touches the ear.
How long do they last?
Plastic friction backs hold for a while but loosen with repeated on-and-off use. Expect to replace them more often than metal butterfly backs.
Can I use them on heavy earrings?
They grip light studs well. For heavy or dangling earrings, a metal back with stronger tension is a safer choice.
What is in the bag?
The bag contains about 2000 clear plastic ear nuts, each roughly 4mm wide and 3mm long.
Where is the Plastic Ear Nuts, Earring Backs, Clear, 3x4mm, Hole: 0.4mm cheapest?
At Amazon, for $3.57, as of our latest check.
