Price is for five pairs of ear studs with SS nut lug. The flat earstud is approx. 5mm pad round. Titanium holds up in the kiln. Titanium is also used in the medical industry as it is strong and the body does not reject it.
Pam East has an amazing video on how to embed titanium into metal clay, see in pictures. These studs will work with base metal too. --
Take the nut lug off, finish your fine silver clay piece and attach the flat pad to your piece with syringe or embed in the clay.
