Review on 📱 Convenient 3-Pack Adhesive Phone Card Holder: Stretchy Lycra Double Pocket Wallet Sleeve Sticker for iPhone, Android & All Smartphones – 2 Navy Blue & 1 Black by Roxana Kotarba

I replaced the old rubber/silicone card case with these and they are a billion times better! I can put more in my bag and the outside pocket is handy too. The only real downside for some people will be that if you put a lot of cards in your pocket and then decide to only carry one or two, it's likely to stretch a bit and not hold the card securely. It's not a problem for me and I have no problem with things falling out. It's also much more durable than the free sticky card sleeves you can get elsewhere - they used to tear very easily - they've held up really well so far.
