Part of why the Warmachine and Hordes dice sell so well is because they come with a tin to carry tokens, cards, and a marker, as well as the dice.
But, yes, I've got 4 sets of PP dice (made by GF9) and their respective tins.
Of course, they've only got 9 different factions, currently, so their cost may be lower.
But, if Mongoose were to go that route for dice, I'd definately buy a couple of tins, at least.
