There are big dice... and then there are mega dice. This aptly named D20 is the king of all dice, spanning an impressive 68mm from tip to tip. This is over 4 times larger than the standard 16mm D20s we're used to playing with. Made from a solid silicone, the Mega Silicone D20 is slightly flexible to the touch, doubling greatly as a stress ball or something to figet on your desk with. Weighty to pick up, the dice roll uncontrollably for moments before coming to a stop.
Impractical as it is, the Mega Silicone D20 is actually super fun to roll. Pick one up and see for yourself.
