The Mask BN Troc's Volants
Set of 30 (1-30)
When looking at the backs of the Tazos, the large notch is either next to the V of Volants, or above the B of BN Troc's. Each number is available with the cut in either position.
It's also easy to identify the variation by looking at the 'direction' that the large notch faces - the point of the notch will face one direction or the other.
