Oh yeah, these combat dice are fantastic. The ones that I have that are showing some wear I have used A LOT. With the dice all tumbling together and banging into one another, eventually there are going to be a few small nicks here and there. I don’t think there is any way to keep them in pristine condition other than not using them at all, and what would be the point of that.
That idea of encasing them in another layer of clear acrylic is interesting. However, like Rorschach said, it would probably up the price. Also, if the layer of acrylic wasn’t 100% even, it might affect the roll of the dice. Like maybe every roll ends up in a “5”. No hits even with battleships or bombers, yet no good for tech research either. I think “5” is the most useless number as far as dice rolls for A&A is concerned.
