These wallets typically hold 2–3 cards securely in the leatherette pocket.
They are made from leatherette (synthetic leather) construction.
They include built-in RF-blocking technology to help prevent unauthorized contactless scanning, and are described as bump-, scratch-, and scuff-resistant for everyday protection.
An adhesive metal ring is included so you can add a magnetic attachment to non-MagSafe phones or cases, allowing the wallet to attach magnetically.
Typical dimensions are listed as 3.75 inches (H) x 0.3 inches (W) x 2.53 inches (D), and the weight is listed at about 0.1 pounds. Verify the listing if you need exact measurements for a specific case or phone.
Phone cases under 4 mm thick are recommended for optimal magnetic attachment.
Cards remain held securely but are accessible—typically removable with a quick thumb swipe.
