The Rattle Toy from Kay Bojesen takes the form of a ring with a small ball fitted through its center, designed to spin and slide freely with the lightest touch. Made of untreated beech, the toy was first designed in 1932, with the wood left unpainted by intention, a choice the designer felt left more space for imaginative play. The dimensions suit small hands, and the smooth, splinter-free surface makes it comfortable to grip and hold.
