Verus Leather Wallet Case
If you didn't get a leather G4 but wish you did, this is the case for you. Verus has a limited edition Coffee Brown leather wallet case for the G4 that should suffice. Delivering a two-tone light brown and dark coffee brown PU leather design, beautiful stitching in the leather to match the G4, and it holds three credit cards plus cash.
The Verus leather wallet case also states it isn't compatible with the leather versions of the G4, so if you bought the plastic G4, this is the perfect alternative to still get that premium leather look and feel.
