How large are these zombies, compared with say Artizan or Copplerstone?
I have no side-by-side comparison pics, but they should be very similar to the Germans, which are "31mm to top of head".

In that case, and from Keeper's comments regardingn their size, put me down for 3 or 4 packs. These will be perfect as opposition to the Copplestone Neo-Sov figures I'm using as the basis for my Soviets (with a few conversions, of course)
