Changing a JewelPop insert is a simple and elegant process. Simply apply a little pressure while pushing down on the insert with your finger. You will hear a reassuring pop or click indicating the JewelPop is in position and secure. To remove and replace with a different insert merely push from behind with your finger or use the small plastic JewelCap that comes with each jewelry design and the JewelPop will pop out. It’s that easy, very secure and no special tools are needed.
