Hi Steve
They have stopped producing all resin now and only supplying STL files for new releases. He stopped shipping to the U.K. a while ago too saying it was too complex, this may have been before Brexit from memory. When he did ship to the U.K. his shipping costs were high. I don’t think given the cost of the kits, shipping and tax many made it to the U.K. at all.
I’ve been offered a Chromonaut which isn’t on my list, if it’s on yours let me know and I’ll hook you up with the seller.
cheers
Neil
