They are 15mm, and very nice looking 15mm at that.
If I still played 15mm fantasy more than once a year, and didn't have half a box of unpainted 15mm fantasy pewter, I'd be spending a lot of money with Splintered Light. The catmen are cool, and I love the fact that their undead line includes undead centaurs, undead dwarves, and undead varients of several of their other races!
