BEADNOVA Earring Backs for Studs Rubber Plastic Silicone Earring Backings Clear Secure Pierced Ear Studs Backs Stopper Safety Hypoallergenic Ear Post Backing for Hook Earstuds (200 pcs)

Product is much smaller in size than expected. I am 76 yrs old with arthritic fingers and purchased these because the photo makes them loo much larger than they actually are.There should be something like a dime or pin in the photo to give a reference for size. If I had known how small they really are, I would probably not have purchased. Hope this is helpful.

What is there to say? You get plenty of backs for your post earrings in this item. Have fit every earring I've used them on, feel secure. I use them for my "good" earrings. The ones with 10k and 14k backs that I don't want to lose in public areas where you know you'll never find it.(Concerts, amusement parks). Also on granddaughters earrings for same reason. Even keep a couple in my purse to give to people trying to find theirs! They work, don't smell of chemicals, have had no skin reaction...all around good backs.

I'm elderly and I like the earring backs that have a bit if a rim on them so they are easy to hold. The rim on these are almost nonexistent. Quite disappointed.

Jewelry artist here - I bought a couple brands to test out, and this one was about 4.5m, which matched the description. Most of the other brands on Amazon are 3mm - 4mm, so don't be fooled by their pictures. I still found them quite small and too tight for easy earring removal, so I'll be returning them (and keeping the other one in the photo, 5mm on the left). Quality was just okay. It was packaged well on the outside, but the actual silicon backs had several shape inconsistencies (minor defects).

Good price. The backs go on good. The only bad part is after time the holes get loose so they slide off the earring a little. Good news is you get a ton and their cheap so after enough wear you replace them.

The box came in kinda broken and didn’t hold very well, I had to transfer it to a ziploc bag so it wouldn’t fall out, overall the product was very hard to put on and remove from the back of the earrings.

Okay, these are GOOD and I'm really happy I purchased them. They fit my earrings very well and do not slip off - so I'm assured I won't lose an earring. And I love that they come in the little box, makes it so easy to use.

I bought these because as a busy mom, I like to just put in my studs, and I wear the same earrings for months and months at a time. I don’t like to take the time to change my earrings. Now, I’m not sure if this is something I should have known was going to happen with this material, but the backs ended up getting completely hard, no longer the soft, squishy silicone feel to them, and they became hard and basically fused onto my earrings. My husband had to cut my earrings off, so now those earrings are gone and ruined.
