Beadaholique5005080 Sterling Earring Backs, 4mm, Silver, 12 Piece (Pack of 1)

Way too small to fit to any earring. Don’t bother

Useful to have as spares, always remember to take a few when I go away too!

Exactly as described by the seller, good quality with reasonable price. Be aware that 4 mm is very small and it only fits earrings with a thin post (the pointed part that you stick through your ear)

Far too small to even handle and far too small to use with any earrings that I own. No idea what these are designed to go with. 100% pointless.

Not suitable for the earings i had the holes where too small

Most of these didn't have holes in them - i thought the price was too good to be true and i was right!
