We had a major hiccup in the form of a pricing issue with the PVC Behemoth. Our factory had thought it was 1/2 the size that it was and had quoted at that scale. So, when we went back for our final quote, the price shot up to something that was... unattainable. The only course of action left for us was to try another material, in this case Resin. We don't like Resin and it wound up being double the price, but rather than giving up, we decided to offer our backers a refund or to upgrade - and at least we could still offer pre-painted.
We're not happy about it, but we decided it was a better option than just giving up entirely on our big beastie.
The Clawed Deviant and Mermaid (from our Kraken KickStarter, which has been remodelled) will still be PVC.
