Short answer: For the thinnest, most minimal look on the standard iPhone 18, the iPhone 18 Aluminum Frameless Case ($61.88) uses metal corner bumpers and no back panel to keep the phone bare and light. For a slim but fully wrapped Pro Max, the iPhone 18 Pro Max Glossy Magnetic Case ($44.99) gives a sleek glossy shell with built-in magnets. Choose the frameless case for barely-there metal style, or the glossy magnetic case for a slim shell with full-back protection and MagSafe.

Which case is actually slimmer?
The Aluminum Frameless Case is the thinnest because it removes the back panel entirely, leaving only corner bumpers. You feel the real phone in hand. The Glossy Magnetic Case is still slim for a full case but adds a thin back layer all around. If minimal thickness is your top priority, the frameless case wins; if you want slim plus complete back coverage, the glossy case is better.
Which protects more of the phone?
The Glossy Magnetic Case covers the entire back and sides, guarding against scratches across the whole body. The frameless case focuses protection on the corners and edges, leaving the back exposed. Frameless owners accept some risk to the back panel in exchange for the thinnest possible feel.
Which phone does each fit?
The Aluminum Frameless Case is set up for the standard iPhone 18 near 6.3 inches, while the Glossy Magnetic Case fits the 6.9-inch iPhone 18 Pro Max. Buy the case matched to your exact model for correct alignment.
Do both keep MagSafe working?
Yes. The Glossy Magnetic Case has a dedicated magnet ring for firm snapping. The frameless case leaves the phone's back open, so MagSafe accessories attach directly to the phone with full strength. Either way, magnetic charging and mounts work.
