ALL PHONES - Cardly stick-on Phone Pocket sticks to IPhone, Galaxy, and all other smartphones. It also sticks to most cases. ***Note - iPhoneX/8/8+ has an anti-fingerprint coating on the back of these devices that doesn't allow 3M adhesive so we recommend a case with these phone models.*** REPLACE - Replace your wallet with a phone pocket, easily put credit cards in the back pocket and cash or keys in the front. TWO UNITS - You receive the two flag units in the image. Save one for later or give one to a friend.
