THX! Hmm, an 18mm, that's unique.D6 is 18mm. D20 is 23.7 mm.
$20 for my favorite set of eleven dice is a pretty good price for me! I like the extra chonky, big easy to read numbers and extra D20 and D6s.I've seen them at our local LGFS. They're overpriced, you'd be better off with a Chessex set and a little bit of Google (latter totally optional).
