BrickEconomy Member Review
“Millennium (or Millennia) is a unique Slizer set, offering two distinct builds: a towering titan and a motorbike-riding figure. The titan, though large and imposing, has an odd design with thin limbs and leftover parts, while the bike is more solid but less exciting. Special gold and high-power discs add a collectible appeal.”
