A stack of flexible sheet material for use in a dispensing device for dispensing individual sheets. The sheets are stacked with alternately opposite edges of successive sheets coated along one edge with a narrow band of readily releasable repositionable pressure-sensitive adhesive. The dispenser comprises a container having a pair of sidewalls connected by a top wall which is formed with a transversely extending rectangular opening extending in the direction parallel to the sidewalls. The stack of sheets are placed within the dispenser such that upon removing the uppermost sheet in the stack the adhesive coating along one edge of the sheet parallel to the opening and adhered to the free edge of the next sheet in the stack will cause the next sheet in the stack to be withdrawn at that free edge through the dispensing opening upon withdrawal of the adhesive coated edge of the uppermost sheet.
A stack of flexible sheet material comprising a plurality of sheets disposed one on top of another, each sheet having a band of relatively releasable repositionable adhesive coated along one edge thereof and the sheets are stacked with the adhesive coated edge of each successive sheet disposed along alternate opposite edges to maintain the sheets in said stack.
