Using this Lilith - inspired phone ring holder is easy. First, make sure the surface of your phone or case is clean and dry. Then peel off the adhesive backing and stick the holder firmly in your desired spot. When using it, you can use your finger through the ring to hold your phone more securely or use it as a stand for watching videos. Remember to keep the surface clean before sticking the holder to ensure good adhesion. If it gets dirty, you can gently wipe it with a soft, dry cloth. Avoid exposing it to excessive heat or moisture as this may affect the adhesive quality.
