Abstract: A two part button system provides secure and easy snap-on/snap-off action between a domed, perforated, flexing decorative top piece and a button base member attached to fabric or apparel. When the parts are in their usable positions with respect to one another, their configurations create a small crevice between opposed perimeter edges. Separation and removal of the top piece from the base member occurs only when a compressing/prying force is applied in the crevice, allowing the top piece to be easily and promptly lifted away from the base member, and optionally replaced by a substitute top piece thus changing the button system appearance. The decorative options for top pieces are unlimited, allowing for a traditional looking and functioning base member that is connected to fabric or apparel in the usual fashion, but able one-at-a-time to accept numerous and various decorative top pieces as desired and changed at will.
