Mega Bloks® HALO® UNSC Mammoth (97174).  The condition is brand new, never opened, with the box in excellent condition (see pics). The set is shipped via USPS Priority 2/3-Day Mail within a protective box. I pay for shipping (domestic only within the continental United States, i.e., I do not ship to Alaska, Hawaii, or any of the U.S. territories). 

The M510 Mammoth siegework has no equal in size, firepower, or tactical faculty within the UNSC's mobile planetside support contingent, making it one of the most powerful ground assets ever designed by humans. At roughly 70 meters in length and carrying numerous mounted support weapons and materiel caches, the M510's most significant attribute is its topside MAC, designed to target and eliminate hostile vessels, weapons, and even fortifications residing in terrestrial or even suborbital positions. Ideal for kids ages 8 and up!
