The core is some kind of fairly dense metal (possibly iron/steel?) and then has different metals on top to colour them. I chose copper and gunmetal colouring.
Would you say those dice are…weighted?
…i have difficulty getting good rolls out of heavy metal dice: they kind of plop down with a thud and just. STOP.
…that and they’re terribly hard on whatever rolling surface i use; towers seem to be the only way to get a reasonably random roll from them and those grow beaten-up by heavy metal dice in pretty short order…
…i wonder if the more-rounded edges roll any better?..i have one hydro74 licensed set similar to those pictured here; i should compare them to my sharper-edged ultrapro heavy metal dice…
