i assume you're referring to the MG? it's p-bandai, limited release.
price will confirm be higher than normal. but you can find them at garage store somewhere here in this forum, or any shopee or lazada (hopefully).
or look around at 2nd hand store.. you could try find it at amcorp mall though.. good luck bro.

timesquare fantasy might have them? just probably. they sometimes have those random rare stuff there. price-wise,   you must be willing to fork out

you could buy the expansion part instead and get a normal verka v2 gundam though (do take note the supposedly gold part is just flat gold-ish yellow)

someone could correct me if im wrong
