The third style for wallet cases is the completely hidden wallet. Spigen is one of the most trusted smartphone case manufacturers around, and now they make a pretty great wallet case for the Galaxy S9 and S9+.
Spigen's Slim Armor CS completely hides your credit card, so no one knows about it. This case uses the popular dual layer design. The inside is a soft and flexible TPU material, then they add a hard and durable polycarbonate plastic to the back and sides. However, that hard plastic has a hidden door that slides down, revealing a slot for two cards or a card and cash.
You get the protection we know and trust from Spigen along with the convenience of a wallet at the same time. Buy one in any of the five colors available at the link below.
