Collector and Investor Standing
Creator's 3 in 1 line appeals to collectors who like a set they can rebuild, and the Space Mining Mech gives them plenty to work with. Its posable limbs, spinning buzz saw and changeable expression make it a lively little machine. For investors, that familiar line appeal keeps the case respectable rather than remarkable.
