Scale- These guys are 28mm scale, which means they are a whopping 18-23 mm high, depending on what’s sprouting out of their heads.
Genre- Period Fantasy… unless you know some other genre that would have undead goblins. If you play modern but really want some zomblins, maybe you could make them into little Trick-or-Treaters. The heads are big enough that they could be masks.
Parts ‘N’ Bits-
The set doesn’t come with any extra anything, but see bases below…
The bases the set comes with are these gorgeous, sculpted, beveled, 20 mm square bases. If you don’t play on square bases, that doesn’t help you much, but honestly, given the price of the blister pack, you’re kinda getting them for free, and they’re beautiful, so don’t complain.
Not really something you are likely to have a specific need for, nor likely something to build an army, game, or anything else around.
