This cell phone card holder is made of stretchy Lycra fabric with self adhesive sticker, which holds the content of the pocket from falling, even when the phone pocket is upside down. Much more soft than silicone and leather card holder, the lycra card holder is suitable for back of phone or phone case. The card holder has two pockets that fits multiple cards such as ID card, metro IC card, credit card, driver's licence, business cards, membership and even earphones etc. The attached X-shaped bands on the pockets allow you to hold your smartphones easier than ever.
