This is a completed action toy designed for collectors.
Part of the "Action Monster" series, this is the 2005 version of the Baltan Seijin, as it appears in Ultraman Max! Its eyes light up and when you move it, it makes a cute little alien sound. Its lobster-claw arms are poseable, too. Comes with test batteries, but these won't last long, so you'll need to buy it proper LR44 (watch-type) batteries; it takes 2.
