It is a official Samsung product called the 'Clearview Cover'.

Originally $90, this case was the go to if you wanted to unlock all the cool features that Samsung had to offer with the S9.

The phone detects the case and allows the time and notifications to be seen through the display cover if you enable 'always-on-display'. The case also has the ability to prop your phone up so you can place it on a surface for viewing. Lastly, it detects when you open it up, waking up your phone automatically.

Price is negotiable.
