Purchased these last July, and have finally gotten around to assembling and priming them. There are over 60 models in the box!
The minis are a kind of rubbery resin, so cleaning the flash and seam lines was a real pain in the arse. It took a lot longer than forgeworld or finecast resin to prep.
Because they are resin, I had to prime them with an aerosol spray. I used the painting stick technique I saw on a blog years ago, and it made batch priming a snap.
I'll start painting the minions first, so that I can develop an anime style that I'm comfortable with before painting the hero figures. I'm so used to the grimdark of 40K that I'm sure it will take me a while to shift gears.
