I have the two bootlegs. I actually prefer the bootleg Heisei Ghidorah over the official SH MonsterArts version, for some reason. There are slight differences.
Best is to buy them pre order from reputable stores like Geekloveph. Once they arrive its very difficult to get them. Usually FB Marketplace or groups like Godzilla Collectors Philippines. We also sell some from time to time. Be sure to follow our Facebook page.
