All of our Switchables earring products are handmade with a LEAD-FREE solder. After each piece is crafted , it is then electroplated with a silver finish to give it an everlasting shine. This will keep your jewelry from tarnishing as you may have seen with other brands. The earrings are HYPO ALLERGENIC, surgical stainless steel, and most pins have a pendant finding on the back giving them the ability to switch into necklaces! These are great for all occasions! Make sure that you take a moment to view its giant counter part under our Switchables nightlight and/or stained glass categories
