MagSafe Compatible Ring Quantity: 1 Color: Silver Includes Installation Guide and Accessories This is a metal ring that makes standard cases compatible with MagSafe. I am selling this because I had one left over from a pack of two. I used it with an iPhone 14 Pro iFace case, and it worked without any problems! I'm not using it anymore because I changed phones, but I think the magnetic force is quite strong. The following is a copy of the product description: [Compatible Models] iPhone 17 / iPhone 17 Pro / iPhone 17 Pro Max, iPhone 16e/16/15/14/13/12/11 series, Samsung Galaxy S24/S23/S22/S21/S20, Google Pixel 10 / Google Pixel 10 Pro / Google Pixel 10 Pro XL / Google Pixel 10 Pro Fold, etc. Please see the product description for a detailed list of compatible models. This MagSafe sticker can be removed once applied, but it cannot be reapplied. [Easy Wireless Charging] Automatically adjusts the position of your smartphone on the MagSafe wireless charger, allowing for easy wireless charging by simply placing it on the charger, without worrying about misalignment. [Doesn't Get Hot While Charging] This ferromagnetic ring is specially designed so that your smartphone does not get hot during both standard and magnetic wireless charging. [Easy to Apply] The intuitive positioning guide makes it easy to apply the ring to the correct position on compatible models. The MagSafe ring can be removed once applied, but it cannot be reapplied. ⚠️ A positioning clip is included with the installation tool. ⚠️[Important] Be sure to attach the metal ring to the outside of the smartphone case. It is necessary to apply it to a flat and smooth surface of the case. This product is not compatible with leather cases, liquid silicone cases, or smartphones without a case. Also, please refrain from attaching the ring to the inside of the smartphone case as it may affect the magnetic force.
