Our latest rig-arm with bigger balls and (yes) bigger joint plates has been available on our Shopee e-commerce store. Bigger ball-joints mean sturdier and lift more weight compare to our V3 standard ball-joint. V4 is an upgrade for those who want sturdier ball-joints or often over twist the hex key during animating, or for food and macro photographers who want stronger rig-arm for moderate weight objects.
