Bandai Builders Parts & Option Parts
Once upon a time, Bandai was steadily releasing a line of first-party "Builders Parts HD" that featured everything from V-fins to emblems and Zaku piping, all cast in high-detail molds and in an easy-to-customize gray color. After nearly 50 releases they stopped and moved on, but many of them still come back into rotation and can still be used in all your custom Gunpla projects!
