My order of the spincast plastic Goblins arrived today, very prompt service and extremely well packed.
The figures themselves are excellent. No casting flaws, no flash and superb surface detail, absolutely 1st rate castings. Plastic is quite rigid and even the extremely thin (too thin really) weapon shafts stand bending back and forth several times before snapping. Cuts very easily with craft knife and simple to drill cleanly with a pin vice. I am very impressed with the quality of this material, equal to any resin figures I have(wargame or collector 54mm) and far far superior to the dreadful GW finecast material.
I do not have Otherworld Goblins to compare them with but these guys tower above GW Goblins/Night Goblins and have even bigger heads. Much to my joy though, they are a perfect match with my Rackham Goblins (Oriental and Strohm styles). Legs and arms are a bit scrawny in comparison but the heads are a perfect match. These are 22mm tall, 25mm to top of helmet and 29mm to tip of horns.
