Phone accessory that keeps cards and small essentials close at hand. Slim and practical, Sinjimoru Mobile Phone Card Case frees pockets and trims handbag clutter. Will the slim stick-on adhere reliably to modern glass-backed phones or is a case required?
⚡ At a Glance
- • Attachment Security: Flap cover combined with strong 3M adhesive keeps cards concealed and held firmly
- • Best for: Minimalists and commuters who want quick access to cards without a wallet
- • Not ideal for: Owners of glass-back phones unless the card holder is used with a compatible case
Slim stick-on card holder uses built-in 3M tape and a flap cover for secure storage. Designed for flat-backed phones or for use with a phone case on models with glass backs.
Secure, concealed storage – with a protective FLAP cover
FLAP cover design prevents direct exposure of card information and holds cards tight inside the pocket. The cover is shaped to maximise security when cards are inserted.
Card details stay hidden from view and cards are less likely to fall out during everyday handling.
Reliable phone attachment – thanks to built-in 3M adhesive
Included 3M tape sticks the pouch to flat-backed phones or to a phone case and is engineered for firm adhesion. The tape is also designed for convenient removal without leaving residue.
Phones with flat backs gain a secure card pocket, and cases make the accessory usable on glass-backed models where direct adhesion is poor.
Compact multi-use pocket – with capacity for up to five cards
Internal space accommodates up to five credit, ID or security cards and can also hold folded notes, keys or other small items. The slim profile keeps the added bulk minimal.
Carry a handful of essentials on the phone, reducing the need for a separate wallet while keeping the phone pocket-friendly.
