Abstract: A decorative housing for a stapler includes a casing and a bottom plate. The casing includes a first cavity defined in a front portion of the casing to receive a press cover of a stapler and a second cavity defined in a rear portion of the casing. A cover is attached to the casing to close the second cavity. At least two liquids with different specific gravity are injected into and fill the second cavity. The liquids do not mix with each other. Multiple floating objects float on the interface of the liquids. The decorative housing for a stapler can promote visual appearance and add value to the conventional stapler.
