You wouldn't normally associate aircraft-grade aluminium, anodised stainless steel finishes, and designs milled out of a single block of billet aluminium with a mobile phone case, but that's exactly what is on offer with three of the latest iPhone 4 cases.
The ElementCASE Vapor (US$79.95) is machined from a solid block of aircraft-grade aluminium, with laser-engraved graphics and a "shock absorbing" liner, while the Atomic Billet iPhone 4 case (US$69.99) is also made from aircraft-grade billet aluminium and features a lifetime colour quality guarantee. Slightly less expensive is KarasKustoms machined iPhone 4 case (US$49 including shipping). The anodised aluminium design also features delrin spacers and stainless button heads. Leaving aside the fancy descriptions, we think they look pretty cool.
We've requested these three cases in for review, so check back soon for a hands-on look!
