Apple announced that its new iPhone X and XR models would be made with stainless steel.
The company said the stainless steel would allow for the new phones to last longer.
In addition, the stainless would be corrosion resistant and be a great fit for a larger iPhone case.
The stainless steel was available at the Apple Store for $399 for the iPhone XR and $449 for the XS.
The stainless steel iPhone case is the same as the iPhone 7 case, which is currently the most expensive iPhone case in the world.
Apple says it has already sold 1.8 million of the new iPhone cases and has orders for 3 million more.
