This is the Lid of the Case for the Large Futhark Runes. The Base is listed separately from the Base, so that you can have the option of printing each in a different color. Of course, making the top and bottom match, is always a good option.
The Lid of the case has the Nordic Runes for "Futhark" spelled out on it.
The Design of the case is themed to resonate with the Runes themselves. Similar Forms, Similar Impressions.
The lid is designed so that it "locks" into place. On the ends of the lid, it has a "clip" designed into it, so that it snaps down onto the base. For this to work, the user needs to gently pull end of the lid outward while pressing down on the lid. Its pretty self-explanatory, once you hold the case in your hands.
