Seriously, there were no differences whatsoever between normal and premium box kit except for the picture on them, but of course, the 'premium' word alone is enough for the die hard fans to hunt for the kit. I got another premium unicorn mode box, this time for the Banshee. Therefore, when Bandai announced that they will release RG Banshee in February 2018 which was coincident with my 'free' time, I knew that I shouldn't let the chance went away. Unicorn, still in 'development stage' since September 2017
The right leg and two feet were the only parts of the kit I could finish. Sadly, I was too busy for completing the kit because of my studies, experiments and exam. When Bandai firstly announced RG Unicorn Gundam for release in 2017, I was among the most hyped people in the world and even able to get the first batch kit (because I live in Japan), the premium unicorn mode box.
