The skin for the S23 ultra comes with different cut outs for the following sections:
back glass
Camera lenses
Sides, top, and bottom
The cut outs and sizes of the skins are perfect for what they are, but I just wished that they had provided a larger cut out for the camera lenses as the S23 has the lenses almost in-line or slightly recessed from the rings surrounding the lenses. If this lens skin was for an iPhone then it would have been perfect because their lenses are raised from the rings and if you put a skin on the lenses then the phone rests against the skin when you put it down on a table. However, since the skins for the S23 only cover the lens, the phone does not rest on the skin but rather the rings which surround the lens. I would have liked slightly larger cutouts for the camera portion so that I could put down my phone without worrying about scratches on the camera rings.
Apart from that one qualm, the rest of the skin is great and the installation video helps.
