400pcs Hypoallergenic Stainless Steel Earrings Posts Flat Pad Blank Earring Pin Studs with Butterfly Earring Backs for Jewelry Making Findings (4mm)

I have used these to make Lego earrings and they have worked great! They work awesome with some E-7000 and an overnight dry. Very durable!

I bought these to turn my vintage clip on earrings into pierced! These were nicely packaged, easy to work with, and best of all, they caused NO IRRITATION when I wore the earrings. My only issue would be that I wish they were a tad longer, but they worked perfectly fine. Highly recommend.

Exactly what I was looking for. The size is great and they are very durable. Perfect for the earrings we make.

Stainless steel

No irritation and easy to use

We didn't receive as many earring posts as advertised. We were left with a lot of extra backs, and there weren't 200 of the posts. The product itself is great, I just gave it 3 stars because we didn't receive the quantity that was advertised.

My boyfriend makes earrings and these are easy to use and easy to attach to the design! We love them!!

These earring posts are great for making your own earrings. The backs fit into the posts perfectly, which is an issue I’ve had with other earring parts.
