Abstract: A folder and method of making a panel with a plurality of foldable tab extensions. The extensions include first and second regions extending away from the panel, and having scored fold lines therebetween. The uppermost tab region has a releasable adhesive as does a portion of the panel. The panel has a releasable coating or surface such when the tab extensions are folded, either at the first or second region along the fold lines, adhesive on the second region will mate with surface on the panel. To reduce memory effect at the fold, the score lines can be triple scored by parallel two or three parallel score lines. The central score line can be shallower than the parallel scores on either side thereof.
