Material & Craftsmanship
The copper core is polished with a clean, even surface, and the center hole is precision-drilled to 0.7 mm. The grooved cylindrical base adds a secure contact point for the stud post, so the back stays in place through daily wear. The compact 5 mm length keeps the back discreet behind the ear.
Fit & Detail
The 0.7 mm hole fits common stud earring posts, and the friction lock holds firmly without extra parts. The flat top sits flush against the lobe, and the grooved base makes removal easy. These backs work as replacements for lost or worn stud backs on daily earrings.
Wearing & Scenarios
These backs suit everyday stud earrings, fashion earrings, and replacement kits for jewelry repair. The gold and silver options match most earring tones, and the compact size keeps the back comfortable through a full day. Wholesale orders can mix colors and quantities in one shipment.
