Apple teased iPhone X-exclusive AR Snapchat Lenses at the phone’s launch event last year, and today, Snapchat is finally releasing them. Only iPhone X users will be able to see the three lenses that are available today, thanks to the TrueDepth front-facing camera of the devices. Those lenses include a Mardi Gras-esque mask, a Day of the Dead skull, and a pretty gold-plated eye cover.

You’ll immediately notice these lenses more tightly sticking to your face, particularly around the jawline, at least going off Snapchat’s provided photos and videos. Snap says the lenses should reflect the surrounding light more realistically. It also says the TrueDepth camera lets it blur the background in these lenses and accurately apply small details and 3D objects. You can see them in action here:
