Spigen iPhone 18 Pro Max / iPhone 17 Pro Max Case – Crystal Flex (MagFit)

The Spigen Crystal Flex (MagFit) is a clear, flexible case for iPhone 18 Pro Max and iPhone 17 Pro Max. Its Clear White finish pairs a transparent shell with a visible white magnetic ring. Pick it if you want the back of your phone to show and use a MagSafe charger or mount during the day.

Key Features

• Flexible TPU shell: The case bends at the corners to help you put it on and take it off. It wraps around the back and sides in one piece.
• Built-in MagFit ring: The ring is already in the case and lines it up with compatible MagSafe chargers and accessories.
• Cushioned corners: Spigen's Air Cushion design helps absorb impacts from everyday bumps and drops.
• Raised edges: The borders around the screen and camera help keep those surfaces from resting directly on a flat desk or table.
• Clear finish: The transparent TPU lets the phone finish show through. Spigen uses its DuraClear formulation to help the case retain its clarity.

A flexible clear case for everyday magnetic charging

The thin, flexible shell makes sense if you swap cases often or want a softer feel around the edges. If you prefer the feel of a rigid back, compare a hybrid case with a hard rear panel. If you prop your phone up for video calls, choose a case with its own stand or use a compatible magnetic stand. You can compare those designs with other iPhone 18 Pro Max cases before choosing.

To put the case on, remove your old cover and brush any grit from the phone and the inside of the shell. Seat one side first, then work the corners around the phone and press along the edges until they sit evenly. Set the phone on a compatible charger with the ring centered. Remove a magnetic wallet or another attachment if it sits between the phone and charger.

Check the phone model in Settings before ordering. The Pro Max shell is shaped for the larger phone and its camera layout. The smaller Pro models need their own case. The front stays open so you can touch the screen directly. If you want a separate screen protector, compare its fit with the case lip before installing it.
