Review: Excellent attachments. - I love these card holders. I've had quite a few styles on different cases. The material does get very dirty, so expect discoloration if you get a lighter color. The plastic cover that slides over the cards tends to rip eventually. The adhesive is very strong and will not come off your case without a strong fight. It's meant to be permanent and it definitely is. It'll show signs of wear and tear but they're excellent card holders/grips.
Review: This little accessory has made my life so much easier and more organized. - I'm absolutely thrilled with my Sinjimoru Phone Grip Credit Card Holder with Flap! First and foremost, the adhesive on this holder is super strong and reliable. I've been using it on my iPhone case for weeks now, and it hasn't budged a bit. The flap adds an extra layer of security, ensuring that my cards stay safe and protected at all times. The design is sleek and functional. The finger strap not only provides a secure grip on my phone but also doubles as a stand for hands-free viewing. Plus, the slim profile of the holder means it doesn't add any bulk to my phone, which is a huge plus. I also love how versatile this holder is. It comfortably holds multiple cards, including my ID and credit cards, making it perfect for when I'm on the go and don't want to carry a bulky wallet.

### ⭐⭐⭐⭐⭐ Great product!
*by W***E on January 16, 2026*

I love these. I think this one is about my sixth one on three different phones. The strap works great for my arthritic hands. It’s very comfortable. I’ve had up to four cards in the slot without any issues. I replaced them when they get too dirty from life. The adhesive is really good.
