Abstract
An absorbent product includes an absorbent portion with an absorbent body between a liquid permeable sheet and a liquid impermeable sheet, and flexible flaps projecting from tapering longitudinal edges of the absorbent portion. A first removable protective layer covers substantially the entire absorbent portion and second and third removable protective layers each cover substantially all of a respective one of the flexible flaps. Each of the second and third protective layers is directly opposite the first protective layer along substantially an entire length of a first line along the respective longitudinal edge of the absorbent portion. The second and third protective layers are at least partially separated from the first protective layer by a cut line that follows the respective first line.
