This is a set of clothes or accessories for figures.
From the Hasegawa website:
It slows things down, leads to traffic jams, and makes drivers rather angry, but all that construction really does have a purpose-and the warnings have a purpose too! Ensure that none of your 1/12 scale figurines accidentally walk off into an open manhole or stray into a patch of wet cement with this construction security set. This kit features all the signboards, warning cones, hard hats, and barricades you need to ensure your 1/12 scale figures understand the area is "OFF LIMITS".
Parts come molded in white and orange. Includes stickers
