600 PCS 5MM Hypoallergenic Stainless Steel Earrings Posts Flat Pad Blank Earring Pin Studs with Butterfly Earring Backs and Silicone Bullet Earring Backs for Jewelry Making Findings

I purchased these earring posts and backs for making my own jewelry at home, and I’ve been very pleased with the quality. The stainless steel posts are sturdy and truly hypoallergenic—The flat pad makes it super easy to glue on decorations or stones, and they hold well.The set comes with both metal and silicone backs, which is a big plus. I like having the option depending on the type of earring I’m making. The quantity is great too—perfect for anyone who creates jewelry regularly or in bulk.If you're into DIY jewelry or want affordable, reliable earring bases, this kit is definitely worth it.Only thing to improve would be to add small containers or bags to keep everything better organized.

ease of use, color is good, quantity is great for the price

Perfect for small stud earrings!

They really are hypoallergenic.

I wanted to 3D print some earrings for the girls, and 5mm seems like the size to go with. These were cheap and nobody's ears have turned green yet, so that's a plus.It's a bit irritating that "600 PCS" means 200 rubber backs, 200 metal backs, 200 studs, which is 100 pairs of earrings. Not that I'm going to print more than 100 pairs of earrings anytime soon, but if you're expecting to be able to turn your "600 PCS" into 600 pairs of earrings, or even 600 earrings, expect again. The Amazon listing is clearly labeled with what you get so I'm not faulting anyone, it's just meh.

Easy to use for jewelry

These haven’t seemed to tarnish so far, will be buying again.

I have been consistently buying these for business use for months and typically I am very pleased with them! However, this last batch I have no idea what happened to them before going into the overall package with the other components like the backs etc, but they are beat to hell and many are bent. Again, the actual shipping package was fine, and the inner plastic package where these the tweezers and both packs of backs are was fine but when opening that self seal plastic package and getting these out, this is how the bag appears. Holes all over it, bunch of bent posts, just overall looks beat to hell. I still say it's a good product and I'll take my losses where I have to, but production or packaging wise I'm not sure at which stage of those something like this is happening, and I'm hoping that doesn't become the norm because these are my go to
