Steel-Wheel Road Roller (Qiji 42210-6)

About this set

This KEEPPLEY 42210-6 road roller sits in the Super Transform series and is a small 68-piece build rated 6+ with a 2/5 difficulty. The model is mostly yellow, with blue side panels, a grey steel drum and black tyres, plus a transparent blue cab. It is also one unit in the BA1 and 8-in-1 combiner system, and the box labels it 42210 construction mech, so check the connection points and their orientation as you go to avoid rework later. Build the chassis and drum first, then add the side panels and cab, and press the clear parts in last to keep them scratch-free. With only 68 pieces it is a quick clutch for beginners and kids, and combiner collectors can treat it as a split part for the construction mech.
