I like display cases. Trophy cases are good, but jewelry cases are great. My favorite was a metal and glass jewelry case where the contents could be viewed from all directions. Materials were laid out on the shelf and the bottom of the case. Great for viewing the contents from a variety of different angles.
Currently, I have a glass front trophy case that allows me to view all of my paints and other stored items "head on". Works much better for me than a bookcase, bin, or chest. I do store some Plano boxes inside of it. Overall, it's very convenient.
