Review on ⚫️ Magnetic Universal Rings with Sticker, Set of 2 Magsafe Sticker Magnet Conversion Rings for Magsafe Accessories & Wireless Chargers Compatible with iPhone 13/12/11 Pro Max, Samsung Galaxy S22/S21 – Black by Jon Brazil

Only bought one. I think you should have gotten two. It definitely cannot be removed. So you might think that a self-adhesive leveling sheet would be better if it was wet instead of wrinkled. My leveling blade was wrinkled making it difficult to center on my case. Then I tore it down. No second chance, no second part. I had one on my old phone from another supplier who supplied two magnets and a paper alignment sheet with stickers on them. It was definitely far from ideal. I wouldn't buy it based on my experience. If you can apply it in one try without an alignment sheet, it will work. Otherwise, try a different one, either buy a case with a built-in MagSafe, or don't have one at all.
