Why waste effort on rolling a d% and a d10 when you can break out a d100? Also known as a Zocchihendron (named after it's inventor, Lou Zocchi, who debuted the die in 1985), this translucent blue die has the feel of a rather large, overweight golf ball.
A d100 is useful when making percentage rolls and when rolling new characters. Although not widely used, it is sure to be a conversation starter at your table!
And it does, in fact, come packaged in the container featured in the last image.
