This is a display base or stand.
Molded in black and red to match Sinanju's color scheme, this Action Base is designed to hold Bandai's 1/100-scale MG Sinanju Ver. Ka kit. It can also be used to hold other 1/100-scale models, 1/144-scale models, and kits from their HGUC, HG Gundam Seed, HG Gundam 00, MG, and Real Robot Revolution series.
Action Base 1 Sinanju Version is a plastic injection snap-fit assembly kit that requires very little work to assemble. No cement or paint required! The support pole has an ingenious locking mechanism that allows it to extend or retract and is strong enough to hold the main stand in place. The main stand itself can also be extended upwards to pose your kit in a much higher position. A sheet of custom marking stickers is included for use on the Action Base.
The set comes with three different sizes (8mm, 9mm, and 11mm) of U-shaped holders, peg-type holders, and screw-on type holders (two screws and a nut are included) for attaching the main stand to the crotch of the kit. (The package notes that there may be cases of a kit not able to fit.)
