Pico Spinners has always been children's favorite toy. ENGINO has developed this new series of colorful Pico Spinners, where creativity meets fun! Each of the 4 sets of Pico Spinners contains a special spinner component, a color disc and standard pieces of metal pigments. Two projects can be created with each set, and when all sets are combined, three aircraft and helicopter projects can be mounted. Project instructions can be found on the Engino website and are constantly updated to further improve construction possibilities.
