▶The New Cellessential CellTek Bond Adhesive - Now Sticks to Glass!◀ With the rise of phones made with glass backs, we quickly learned that the 3M adhesive available on the market was not strong enough to stick to glass. It also does not stick well to silicone cases. We set out to find a better adhesive and tested dozens of versions to find one that would stick better to the new glass-backed phones. We are excited to announce that our wallets now contain CellTek Bond adhesive that will stick more securely to glass backed phones than any others on the market! ★Important Note - For customers with glass backed phones please follow the installation card included in the package very carefully. You must clean the glass with alcohol and then stick the wallet on firmly and leave it overnight for 8 hours with the phone resting on the wallet. This will give the wallet the best chance of sticking to the glass. Please also do the same for silicone cases although it is not recommended to stick on silicone cases. There are currently no adhesives that stick well to silicone.
