Securing and Setting Stud Earrings Using the New Holding Pins from Lithic Design January 19, 2023 Kaley I created these non-marring holding pins so that I could set shorter bezels while still securing my work on my ball vise. This video shows examples of setting smaller pieces using various shapes. The materials used are fossilized dinosaur bone, sterling, and fine silver. If you'd like to try them out for yourself, they are available for sale at lithicdesign.com/tools See this product in the original post
