Welcome to Bluefin Distribution!


The Bandai Gunpla Builders World Cup (GBWC) is a yearly contest held amongst modelers to show off their completed Gundam models.  Top modelers from countries such as Japan, China, Singapore, Philippines, Indonesia, Italy, N. America, Thailand, Hong Kong, South Korea, Australia and Malaysia battle it out for the title of Gunpla World Cup Champion.


To determine the N. American Representative to this world competition, a set of U.S. live regional competitions and one online competition open to the U.S. and Canada will be held in 2013. Each convention and the online competitions hosted on and will have its own set of Semi-Finalists. From this pool of semi-finalists, one will be chosen to be the N. American Representative to take names and kick some butt against the world at the Bandai GunPla World Cup Finals later this year.
