An accessorial device includes a flexible elongate member partly or wholly magnetized to form magnetic parts, a coating film with which the elongate member is entirely coated, a coating member with which the elongate member having been coated with the coating film is further coated, two caps fitted on opposite ends of the elongate member twice coated, and a decorative member mounted on the twice coated elongate member. The accessorial device assumes an annular shape of a diameter which is adjustable due owing to the flexibility of the elongate member and mutual magnetic attraction of the magnetic parts.
