The scroll case may find use whenever one needs to transport a short missive in a dignified, weather-resistant container.
Read about how I used one of these to 3d print a time capsule: http://zheng3.com/2013/10/18/home-is-where-the-art-is-part-ii/

Use a medium length of sturdy ribbon to fasten the scroll case snugly between a raven's wings, with an X-harness across the bird's keel.
Can also hold a small quantity of iocaine powder.
