Frame Arms

Frame Arms is Kotobukiya’s original line of customisable mecha model kits, designed by top mechanical artists from across the industry. Each features a fully articulated inner frame that serves as a base for interchangeable armour, weapons, and accessories. Built without the need for glue or paint, the kits encourage creativity and customisation, allowing builders to design their own machines. With its distinctive mechanical style and modular construction, Frame Arms has become a cornerstone of modern mecha modelling.
