I am new to Mini-GT (long time Hot Wheels collector). I am currently in Japan on vacation and would love to pick up some stuff that is cheaper or not available back home in Europe. Will be stopping by Libertywalk and the Minicar a GoGo convention.
I am not sure how exclusive and limited items work. Modt stuff (also blister packages) seem to be preorderable in european shops.
I appreciate all tips regarding how releases work.
Thank you!
