Genko Card Sleeve Wallet Pocket ID Holder Credit Card Case 3M Sticker Backing Cell Phone Pouches for iPhone and Android Smartphones-Gold

I wanted a pocket to hold my club card on the back of my phone, so I ordered this one. I was concerned whether it would securely hold just one card, but it feels quite snug while it will expand to hold more.I just started using this yesterday so can't speak to the durability of the glue yet.Two small things:1. My phone is rose gold, and I ordered a rose gold pocket to match. The one I got is "plain" gold, not gold with a pinkish tinge - so the color does not match as I want it to.2. I was not home when the package was delivered, and a signature was required so I had to arrange a new delivery (with USPS) without signature. I don't know if signature is required because this ships from overseas (China) - of you just want it left at your doorstep try contacting the seller with instructions to that effect.
