From Apple’s official product page:

Thin, light, and easy to grip — this case lets you enjoy the look of iPhone XR while providing extra protection. It’s also crafted with a blend of optically clear polycarbonate and flexible TPU materials, so the case fits right over the buttons for easy use. On the surface, a scratch-resistant coating has been applied not only to the exterior, but also to the interior. Need to wirelessly charge? Just leave the case on your iPhone and set it on your Qi-certified charger.

Puzzling why it took this long. Available for delivery Monday December 11, for pickup Tuesday December 12.
