PopSockets PopWallet and PopGrip are now integrated. Simplify spending by attaching a PopWallet+ to the back of your phone and swap about designs through quick removal of the PopTop. Integrated PopGrip offers secure handle so you can text with one hand, snap better photos, and watch cat videos hands-free. There's less to keep track of when everything is in the same, stylish place, and you can attach a PopGrip right on top. Popwallet is removable. Wallet must be removed to wirelessly charge. PopWallet sticks to smooth and hard cases. Will not stick to silicone, highly textured cases, and many soft cases.
