Every self respecting nerd should have a dice collection, be it large or small. Good for Dungeons & Dragons, board games, Magic the Gathering counters, and the like. I'm especially fond of the twenty-siders and twelve-siders. Hundred-sided dice can be accomplished by combining two ten-siders, and many ten-sided die show two digits for just this purpose. Gaming dice come in all sorts of colors, designs, patterns, and transparencies.
