Thanks for the compliments, I'm glad people think it's cool. I'm somewhat proud of the project myself.
The box was something cheap I picked up at a local craft store because it looked cool and was very inexpensive. I considered using it to carry my dice around, but then decided it would be cool to have a reference of spells at hand for whichever lore my wizard decides to take.
This past week I was watching my dad's trophy store. By the end of the week, this meant I had some spare time as well as a 25 W laser engraver, and a variety of different colored plastics. The results you can see for yourself.
It's meant more to be a reference for my wizard, but I figured I might as well call it the casket, because I could. In truth, very few of the spells my casketus steals are from the core 8 colleges. Too many DoC and WoC players.
