Review on Sinjimoru Stick-on Phone Card Holder - Credit Card, Phone Wallet for iPhone and Cell Phone - Sinji Pouch Basic 2, Black by Roy Boone

Very important first: don't buy white. I've been using it for over two weeks now. Here are my observations: (1) With four cards, the elastic is quite tight and has never lost its elasticity in the last few weeks (2) I have inserted my company key card, subway card and credit cards. I like the convenience: I don't have to pull out my wallet to go to the office or to take the train. (3) I use this on my 6 Plus' plastic bumper and the adhesive is very strong. (4) It is very lightweight so it doesn't feel heavy like other card/wallet cases. (5) As other reviewers have pointed out, the white gets dirty pretty quickly and gets really ugly. (6) Please note, that when you have more cards, it is difficult to take the cards in the middle or in the back because they all have the same insertion depth. (7) iPhone loses its overall look. This product is more for utility than aesthetics.
