I am not sure what you mean by Original ... but I can tell you ... the more you buy ... the cheaper the cost per die for shippign will becomeWhere can I buy some original dice (preferably for not too much money and low shipping cost )
You can try the the links in my links section in particular MANUFACTURERS (Direct and Indirect) ... and ... DISTRIBUTERS
I personnaly recommend GameStation.net ... as they carry most of the dice companies dice
I do not make a point of trying to collect gaffed / rigged / fake dice ... so I really cant help much hereWhere can I find some fake dice? Magic shops don't have them that much apparently.
