Made by Scale Solutions in Sydney Australia, the kit comes with 2 one-piece resin cast cities. Price is  $32 AUS in Australia. It's 78 mm in diameter, so it is small. Casting is quite good and it paints up well. No instructions, none needed. Limitations in detail due to it's small size but what there is looks cool.

I made a custom diorama using a wooden base and some hobby ocean material. It has an activated shield as well which is a camera dome 100 mm in diameter. I used a Tamiya steel Grey for the city color.
