Meet Sol! Stick Sol to the back of your phone for an ideal artistry-meets-practicality upgrade. Our phone grips start with a clear TPU expandable phone grip base. We then lather down a coating of silicone or gel based glue and sprinkle on real shells, gems, pearls, vintage cabochons, natural material, porcelain chips, and other up-cycled bits and bobs. A UV-cured coating of resin is applied on top to seal, protect, and add some extra shine. While sturdy, we ask that you avoid drops, bumps, and falls to prolong the life and quality of your case! TPU expandable phone grip. Adhesive backing will adhere to any non-silicone phone case, hard plastic cases are ideal.
