VEX Robotics Construction Worker Building Sets

Two VEX Robotics Construction Worker building sets. One set is complete and unopened. And one set was opened and I can’t be certain that everything is there. Could be complete but I’m throwing it in for free if you buy the smaller complete set. Each set includes over 180 pieces. Build the Steam Roller and the Excavator. The sets are suitable for children ages 6 and up.
