This 2-pack of Scosche MagicPlates are designed to let you magnetically mount your mobile devices to a MagicMount system (not included). They affix to the back of your mobile device, such as a smartphone, tablet, or GPS with 3M adhesive. Once attached, the metal plates give your devices the ability to secure themselves via the neodymium magnets inside a MagicMount. You also have the option of attaching these MagicPlates to the back of your device's case, or if you own an (optional) PopSockets, they are perfectly sized to fit inside the cap. Use these to give more mobile devices the ability to use a MagicMount system, or replace an existing MagicPlate. To ensure your MagicPlates stick to your device securely, included alcohol wipes should be used beforehand to remove any oils or other residue that can degrade the connection.
