Pretty well. Held the rules, dice and everything in one object.
I think this case will function best as an on-demand 'in the field' ritual prep solution. It's a bit long right now to be carried all the time. Still trying to find a solution to hold the standard caster 'back-up' rituals. (DFM, spirit walk) However, for a mod where a scroll needs to travel and be cast, it's perfect. Set everything up, quack quack ducks in a row, then you can just unroll and 'Begin ritual.'
It's also just a cool prop in general. Maybe donate one or two to the chapter for loot, royal decrees, contracts or merchants. Figuring out some kind of shoulder sling or belt attachment would be pretty helpful.
