This is an absolute bargain for an Incase branded case.
The model is: Incase Faux-Leather Protective Snap Jacket for 13-Inch MacBook Pro Thunderbolt 3 USB-C - Grey which should be compatible with 2020 models including the M1 as they have similar chassis.
This is normally around $80-$100 but the price has been hovering sub-$20 recently.
