Review on ✨ Njjex Wallet Case - Samsung Galaxy S21 5G, Galaxy S21 Case - [9 Card Slots] PU Leather ID Credit Holder Folio Flip [Detachable] Kickstand - Magnetic Phone Cover & Lanyard - Samsung S21 [Black] by Aaron Urena

When you insert a full deck of cards the wallet sticks out too much. Prevents closing. Also, since there is no valve or other mechanism to secure the cards, they will pop out if the wallet portion is tilted down. Not perfect. If there is space for several banknotes in the description, that is what is meant. Tried $4 bills, had to fold in half to fit or mixed fold to fit, further exacerbating space issues. Tape the flap to cover the cards to keep them from falling out. No accounts. And only four card slots are used. The side of the phone was fine, but the magnetic closure gets in the way when navigating without a GPS/compass.
