A safe spinning button necklace toy having a knotless string loop, a rotatable button spinner disposed on the string loop and a pair of protective casings covering the string loop that eliminates a strangulation hazard without interfering with the operation of the toy. The protective casing covers a pair of strands of the string loop, keeping the strands together inside the casing and preventing the strands from separating and creating a hazard. The casing substantially covers two-thirds of the string loop and prevents the strands separating without knotting the strands, allowing the string loop to freely twist when the button spinner is rotated. The casing has a plurality of links covering the string loop providing amusing noises by reverberating when the spinning button spins. A pair of handles on the string loop can be safely fastened together to close the necklace when the toy is not in use.
