An object of the invention is to provide a golf instrument which attractively displays the appearance and quality of golf tools such as golf balls. This is achieved with a golf instrument comprising a golf tool or golf tool package having a hologram wherein there is formed an irregularly reflecting area which irregularly reflects incident light, and there are also formed, within the irregularly reflecting area, both a first regularly reflecting area which regularly reflects incident light from a predetermined angle for displaying an external view of the golf tool, and a second regularly reflecting area which regularly reflects incident light from a different angle than the above angle for displaying the internal structure of the golf tool.
