I finally purchased a Gundam Build Fighters kit to add up to the collection. The kit is the HG Build Strike Full Package, the first Gunpla kit used by the protagonist in the Gunpla tournament in the series. It was good thing that the store Wasabi Toys had this kit in stock at a fair price and shipping. The only issue was the additional day of shipping & the delayed tracking update on the Xend site.
I have decided to buy this kit for the reason that I am curious with the recent detail of the build by Bandai kits as well as that it is my first kit for the series. Here are some pics of the unboxing of the package:
