Abstract
A button comprising a core including a face defining at least one slot and a shaft extending outwardly from the face. The core is preferably made from a rigid material. An outer portion is connected to the core and at least partially surrounds the face. The outer portion is preferably made from a flexible resilient material. A relatively flat cap includes a base with a front side and a back side disposed opposite one another. A foil is connected to the front side and at least one rib projects outwardly from the back side. The rib extends into the slot to connect the cap to the core. The face can define three slots and the cap can include three ribs projecting outwardly from the back side. Each rib extends into a corresponding slot to connect the cap to the core.
