A reusable closure system for providing easy closure and opening of an object such as a sheet forming a barrier. The reusable closure system generally includes a backing member adapted to be secured to an object, such as by an adhesive. A closure member may be connected to the backing member, with the closure member including a first portion which is removably connected to a second portion by one or more magnets. An optional outer closure member may be connected to the closure member, with the outer closure member including a zipper. Thus, the reusable closure system may be secured to various objects to allow for selective opening or closing of the objects in a versatile, user-selected manner.
