The iMac G3 case is back for the iPhone 18 Pro and Pro Max, under a new name and with half the colors. Spigen's Ultra Hybrid C-One is a translucent MagSafe case styled after the 1998 iMac, sold in Tangerine and Bondi Blue, where the iPhone 17 Classic C1 case also came in Ruby and Graphite.

The recipe hasn't changed much. A polycarbonate back sits over a TPU body lined with XRD impact foam, and a printed teardown layer under the plastic turns the MagSafe ring into one more fake component. In the Bondi Blue render, a frosted gray band runs across the bottom and a mock service warning label sits next to the Spigen logo, which is exactly as much fun as it sounds.

What works

  • The camera bump is fully covered, with raised edges around the lenses
  • Camera Control sits under a thin TPU layer that keeps it working
  • Cutouts along the bottom take a crossbody strap or lanyard, for iPhoners who carry hands-free

What to know

  • Drop protection is sold as military-grade with Air Cushion corners, with no drop height given
  • Translucent plastic shows its age: a year-old sibling case looked "worse for wear" to Cult of Mac

The closest hands-on data point is an older case. Cult of Mac dropped an iPhone 15 Pro in the Classic C1 face-down onto bare concrete and found no damage. That was a different case on a different phone, with the same two-piece idea behind it.

It suits anyone buying on looks first, since the looks are the part Spigen documents in full.
