Does anyone know where I can get screw posts in sterling silver with a ball screw on as the back and just the post or disc as the front (to which I will solder earring front) Ideally post thickness of 0.7-1mm thickness.

These are to be used as single earrings on the ear (obviously ) but the back will be behind the "tragus" or "helix" (just google 'outer ear anatomy' to see which bits I mean ), so needs to be a screw on fitting for security and a ball or similar for comfort!

Any ideas of a supplier please???
