This is a replica of the Scarlett Solo red metal casing. It can be printed in whatever color or material you like.

Replacing the case: 
Removing the original red case is not hard at all, just peel back the two lower pads on the bottom, revealing a couple screws. These are the only screws keeping the case on so once unscrewed the red case should slide right off. Then you can slide on the printed case and screw it on.

The printed case also weighs several times less than the metal one.
