Blank panels to fill empty spaces in your eurorack case. Our panels are covered with a beautiful printed pattern of electronic paths. You can place any size blank panels side by side in any configuration and the printed graphic design will always create one continuous pattern. If you prefer not printed white or black surface, just flip over the panels.
