Abstract: Disclosed herein is a method of preparing a magnetic substrate laminated with a PSA and release liner. The method comprises providing a magnetic substrate laminated with a PSA/release liner structure, removing a release liner from the PSA, and reapplying a release liner such that it is shifted in relation to the magnetic substrate to expose a portion of the PSA. A portion of the release liner may extend past an edge of the magnetic substrate, forming a tab to facilitate later removal of the release liner from the PSA. An attachment may be secured to the exposed PSA to create a customizable promotional item which may be further customized by the later removal of the release liner to allow a customized attachment to be affixed to a portion of the PSA.
