STRONGER ADHESIVE - Cellessentials wallet stickers have been redesigned with the strongest adhesive available that will not leave residue on your phone. Our new CellTek Bond adhesive will stick to glass backed phones much better than the 3M versions on the market. Attaches to any cell phone and sticks to most cases. CARRY LESS - Each cellphone wallet case has a pouch making it easy to carry your most important cards without needing a bulky wallet. Keep the most important cards with you at all times such as your debit card, credit card, driver's license, bus pass, train pass, business cards and more. SECURE FIT - The sleeves can hold up to 3 cards securely while feeling confident your cards will not fall out. These silicone wallets are designed to be slim while adding grip to your phone without being too bulky. The thickness of your cards will determine how many you can fit.
