Costyle 4 Pack Slim Card Holder Stick On Wallet Pink Gray Mint Green Rose

Slim four-pack card holder

The Costyle set contains four ultra-thin wallets that adhere to the back of a smartphone, tablet or smooth case. Each pocket is made from stretchy elastic fabric and weighs only 10 grams. The full-cover design holds up to about eight cards plus cash or small items such as earphones. Buyers who want a built-in kickstand or RFID-blocking layer will not find those features here.

Replaces bulky wallets and loose pockets

The adhesive pouches remove the need to carry a separate leather wallet or dig through a bag for transit passes. They are worth adding when you regularly use two to three essential cards and want them instantly accessible on the device you already hold. People who carry more than ten cards or need a coin compartment should look elsewhere.

Peel-and-stick 3M adhesive install

Each wallet uses a reusable 3M tape backing that bonds firmly to phones, cases, mirrors, dashboards or refrigerator doors. Removal leaves no sticky residue, so the pocket can be repositioned on another surface. The fabric retains its shape after repeated stretching, but the adhesive can lose grip on heavily textured or silicone-coated cases.
