This is my second Sinjimoru. The first one I bought was B2 in red. Sinjimoru comes in different lines (B2, B3, etc.) but the only difference seems to be the colors available in each line. The sticker folder has a minimalist design and holds up well. The maximum number of cards I have ever put in my wallet is 3 because the cards pile up and take up too much space in the phone. However, this is just personal preference and not a fault with the wallet itself. I haven't tried inserting other items like headphones, but they should fit. Also, I assume these sticker wallets are for single use only. I did not try to remove any of the covers. TIP: Place Sinjimoru a little closer to the center of the phone so your phone will lift fairly evenly when you have cards in your wallet. Save yourself the hassle of looking for a wallet and your hard-earned cash and just buy Sinjimoru. If it wasn't for the price I would take a few more to put on for sure I have. (Let's face it, we all have a few cases!)
