This is a spectacular magical art for you to put together. It is made with paper entirely (except two little wood sticks). This “V-Twin Engine” has semi-realistic exterior and interior detail. The size is about 70% of real engine. It is powered by hand. All parts are to be cut out and folded. No paint applied. It looks pure and elegant. Moveable parts include a crankshaft, 2 rods, and 2 pistons. The origami-reinforced structures are applied inside the body of engine. The origami-reinforced structures make the model very rigid and keep the pieces in the accurate positions.
