Resin and Clay charms are imperfect but yet perfect for creating a one of a kind theme for your jewelry. We recommend checking the screw in pin to make sure it's compatible with the base you're connecting it to. We suggest a drop jewelry glue (the glue type is up to you, test spot your glue choice) on the base where the pin is screwed inside of to add extra security. Lollipop sticks should be treated the same way at the base of the inserted stick. We have example videos in our bio highlights on our Instagram page.
