Sincase [3 Pack] Ultra Thin Stick-on Stretchy Lycra Cell Phone Card Holder Self Adhesive Credit Card Wallet Cash ID Pocket for back of iPhone, Samsung, Most Smartphones & Cases, Black

What a great idea. Nice quality and shipped fast! I wanted something to hold my daily to do's so I use it with index cards cut to fit. Always have my phone but not always my planner. This way I see it all the time. Good for my drivers license and credit card too.

Perfect

it works

Somewhat disappointed. Holds just a cpl of cards and folded $ bills, or just ear buds as a convenience.
