Resin Dice Set (20) - Robot Legions - One page Rules - Grimdark Future
$69.99
These 16mm dice are made of resin and look amazing, they are also made to be playable, with a good level of contrast.
Note that those are included in the Collector Box. If you are getting the Collector Box, you do not need to get this add-on too - unless you want a second set of course!
