  • Our take on the Rubber Ear Nuts, Earring Backs, Clear, 5x5x4mm, Hole: 0.5mm

    These are clear rubber ear nuts, the soft friction backs that hold stud earrings in place. Each measures about 5mm by 5mm by 4mm with a 0.5mm hole, so they fit standard thin earring posts. They are a cheap fix for lost backs and a good match for small studs and children's earrings. Unlike metal butterfly backs, rubber grips hold better on smooth posts and feel softer against the skin, but they wear out faster and can stretch over time.

    Questions and answers

    Will these fit my earring posts?
    They fit posts up to about 0.5mm thick, which covers most standard stud earrings. Thicker or threaded posts will not go through.
    Are they better than metal butterfly backs?
    They grip smooth posts more firmly and feel softer on the skin. Metal backs last longer and suit heavier earrings better.
    Can I sleep in them?
    Many people do, since the rubber is soft against the earlobe. Check that the back is not pressing into the skin.
    How long do they last?
    Expect them to stretch or harden after months of regular use. Replace them when they stop holding the earring snugly.
    Are they safe for children?
    They work well on kids' studs, but they are tiny and a choking hazard. Keep them away from young children.
