The phone wallet stickers have been redesigned with the strongest adhesive available that will not leave residue on your phone. Each cellphone wallet case has a pouch making it easy to carry the most important cards without needing a bulky wallet. Keep the most important cards at all times such as debit card, credit card, driver's license, bus pass, train pass, business cards and more. 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. Strong 3M adhesive tape allows to be reused. Color and logo can be customized.
