PROBLEM TO BE SOLVED: To provide a positionable and repositionable adhesive sheet. SOLUTION: The adhesive sheet comprises (1) a backing, (2) an adhesive layer having at least one topologically microstructured surface comprising a plurality of pegs, substantially uniformly distributed and protruding outwardly from an essentially planar adhesive layer surface to a height in the range of 15 to 200μm, wherein the pegs have essentially flat tops that are adhesive and account for less than 25% of the total surface area of the adhesive layer and the planar adhesive surface between and around the pegs is greater than 30% of the total surface area of the adhesive layer.
