The MG Gundam RX-78-2 stands out because it represents the classic Gundam design in a larger, more detailed format. For me, it was important to get a model that balanced nostalgia, articulation, and shelf presence.

What I Looked for Before Buying

Before I bought mine, I checked a few things carefully:
