Never had to. I would go for the clear plastic. Seems like the sort of thing anyone who sells ear rings would have????

I bought a pair of baroque black pearl earrings but didn't like the backs. I took them to a local jewelry store and bought some larger gold backs that fit well on the posts. They are a bit larger, easier to handle and keep the earrings firm against my lobes. I switch them out on my other earrings, too. So I would try there. Support your local business.

I usually wear a pair of small twisted 18k hoop huggies. They seem very stable to me, I go running in them. For the others, solid 14k or 18k butterfly backs. A lot of the earring posts have rungs, so the backs don't come off easily. The butterfly backs do vary in size. I've purchased earrings with the backs from various jewelers or once, just the backs.

I bought a package or 1,000 silicone earring backs on Amazon in 2021 for about five bucks, they will last the rest of my life. Never lost an earring when secured by them.

Thanks everyone!

These are the ones I bought on Amazon last month.

@Lars....Does the plating flake off?

I also love huggies earrings. I have multiple pairs, but I usually wear a pair for a week or two (never removing them) before I remember to change them. (Huggies have no backs. They are hinged and click together to make a complete circle.)

I often switch out backs from other earrings if one goes missing or loose - I have lots to spare.

I bought a pkg of silicon backs from Joann or Michaels, I forget which, and like lucillle, I think they should last me just about forever.

I was mad last week, tho, when I discovered the gold back from a favorite pair I was wearing had disappeared some time during the day. I'm thankful I didn't lose the earring too, but still - grrr.

I guess I need to switch out all my metal backs for the silicon ones.

I bought these locking earring backs and they really work. Just squeeze to remove...they slide on like a regular earring back.

I too have a pack of silicone ones for when I need them. Two kinds actually. A little nub kind and also a bigger one that can hold larger earrings. I also have a lot of random backs from finding bags. I make earrings so there's always findings around. And a pair of pearl backs- glass pearls with a silicone insert for the earring post.

I didn't know that there were huggie earrings or squeeze earring's backs. I haven't bought a new pair of earrings in over 10 years or longer. I have so many, I don't need any more. Thanks again everyone. I knew you would have some answers
