[Actually On Topic] Source of 9mm/10mm Dice?

Does anyone have a source, mail order or online, of 9mm or 10mm 6-sided
dice?

A couple of years ago, at GenCon, I bought a bunch of 10mm dice from Koplow
Games. These are perfect for me for marking fighter endurance and numbers
(hence the reason it is on topic). I need some more.

Unfortunately, Koplow doesn't sell directly to consumers, and their web site
is not the greatest. Chessex (which now owns The Armory) has a listing from
November of 9mm and 11mm dice (only one colour, though) coming in December
2000, but it's not on their main catalogue. There's no idea if they have any.

So, I'm looking for an online source of 9mm or 10mm opaque (preferably) D6s.
I'd appreciate any help with this.
