    PRODUCT DETAILS

    Introducing M.S.G Active Booster, a large-scale unit that can be used in a variety of forms! Composed of large left and right booster units and a back arm unit, its design based on smooth curved surfaces is ideal not only for mecha models but also for customizing female characters.

    Model Specifications:

    • Clear parts are used for the frame section. The translucent frame peeking through the gaps in the armor enhances the model's details, and a slide mechanism on part of the armor lets you adjust how much of the clear frame is exposed.
    • Equip it on the back or above the shoulders using the back arm unit for Booster Mode, or arrange it like a shield. An optional part for equipping four units is included, so two sets build an even more impressive silhouette.
    • Attach the included 10 fin-shaped articulated fingers to transform it into Brutal Claw Mode, a giant arm with sharp claws. The fins use 3mm joints and can be used individually for customization.
    • Deploy and fold the parts to swap it with the legs from the thighs down on female characters for Flight Leg Assault Unit Mode.
    • The back of the unit has multiple 3mm connection points for combining with other M.S.G units.

    • Booster Unit x2
    • Back Arm Unit x1
    • Adapter Parts A-D x1 each

    Before You Buy

    Limited & Exclusive Releases: Certain figures are produced in limited quantities or as store exclusives. Availability may be limited, and restocks are not guaranteed.

    Blind Box Items: Some figures come in blind boxes, meaning you will receive a random character. Please check the product description before purchasing.

    Pre-Orders: If the figure is a pre-order item, check the estimated release date and shipping timeline before placing an order.


    How to Care for Your Figures

    Avoid Direct Sunlight: UV exposure can cause colors to fade over time. Store figures away from direct sunlight.

    Temperature & Humidity Control: Keep figures in a cool, dry place to prevent warping or deterioration of materials.

    Regular Dusting: Use a soft brush or compressed air to gently remove dust without damaging delicate paintwork.

    Storage for Extra Parts: Some figures come with interchangeable hands, faces, or accessories. Store them in labeled bags or small containers to prevent loss.
