I've preordered in may 2016,but i didn't received email for color survey. I've contacted dragonbox via whatsapp to take part to survey. Now i'm not sure to reiceve email when my preorder are ready to finish. I want to know an estimate date. ThanksThe survey about the colours should have all been sent out to your registered email account. If you have a preorder you should have received it already (twice if you're German, the first being blank). If you only have a pre-preorder still you have some work to do.
