Not too sure these are actual precision dice as the graphics on the dice could imbalance the dr, imperceptibly to the average minds comprehension perhaps, but only those with the original dots would be acceptable in the norm. If forced to used precision dice I would NEVER accept a dr/DR with those marked with extra information put on them (and never with a left handed throw).Check with Chris at Battle School. I think you can ask for a specific set of dice so no need to buy in pairs. Battle School is excellent to deal with...
