Marble-style cases commonly use thermoplastic polyurethane (TPU) and polycarbonate. Many combine a polycarbonate hard shell with a TPU bumper for impact resistance, and some designs use clear resin for decorative accents.
Marble cases typically advertise several protections: shock-absorbing elements and reinforced or cushioned corners for drops, raised bezels to protect the screen and camera from surfaces, grippy sides to reduce slips, and anti-scratch coatings to resist surface wear.
Many marble cases are designed to support wireless charging. Some models also include built-in magnets or are compatible with magnetic-style wireless chargers and accessory mounts, but check the product listing to confirm magnetic alignment and charging compatibility.
Most marble cases emphasize precise cutouts for ports and cameras and use beveled or tactile button covers to preserve button feedback. That design keeps ports accessible and maintains a natural feel when pressing side buttons.

Many marble cases use anti-scratch coatings and raised bezels to keep the screen and camera from contacting surfaces. Some listings also specify scratch-resistant materials or coatings for added surface durability.
