These custom dice were designed by Joseph Fjelstad, creator of Microgammon, and while they were originally intended for that game, we find they are excellent in many other applications. See our other listings for his multi-variable X-Dice and our clear plastic Dice Box. Truncated D4's: $3ea (bulk pricing available) "These truncated 'caltrop' D4's are slightly larger, roll better, and are easier to pick up, than the traditional polyhedral style." Available in Brown or Cream.
