One player of our group (we played AD&D and Mechwarrior RPG) liked to discuss kc-tier properties of dices. He often said that dices must be ideally symmetrical and have smooth sides without notches that indicate number, because it is related to weight and changes outcome. Side with six is "lighter" than others, for example, etc.
He would be mad if he'd seen your dice.
