Pre-orders for these little gems seem to have been up on RobotKingdom's website for a while. Glad to see that Maiden Japan's original designs are approaching third party status - see the same link for some notably cool stuff for Universe Inferno and ROTF Voyager Bludgeon

For the $55USD asking price, you get $65USD of value based on Maiden Japan's pricing for these painted parts:
$11 Head
$14 Chest
$12 Waist
$14 Shield
$14 Accessory pack (includes axe weapon, shoulder guard, pair of shin guards)
