Because Flexitoys are sized to fit in a child's hands, they are easy to snap and hinge together. Flexitoys have always been synonymous with stimulating children's creativity in open play. With FLEXIBLOCKS and FLEXISWIVELS, anything is possible, from creating a structural simple, jaw-snapping alligator, to assembling a colossal, sophisticated suspension bridge. The FLEXILINKS make other major brand blocks woth with Flexitoys. Our larger sets are ideal for groups of kids or anyone interested in building more complex structures. The impressive Classroom Set is packed in a large, durable container for easy storage.
