Use these clips for when you don't have holes but want to wear earrings. The Earring clips consist of 2 parts that you attach to each other after baking (max. 700 ° C) or after soldering.
Use a good pair of pliers to attach the two parts together. The L-shaped pieces fall into the holes of the foot that sits on your workpiece.
Be sure to roughen the underside of the foot with a file. Then fix well with the original paste and fire after drying for at least 45 minutes at max 700 ° C.
You could possibly drill two holes on the bottom of the foot through which the paste comes through, so that you can secure the foot even better.
