Fastener

A fastening tape, comprising:

• an elongated substrate;
• a plurality of fastening cells on a surface of the substrate;
• and
• a magnetic material in at least one linear arrangement along a longitudinal direction of the substrate,
• wherein each of at least some of the fastening cells comprises:
• a fastening element array;
• and
• one or more barriers at least partially surrounding the fastening element array;
• wherein the magnetic material has a plurality of breaks formed at a predetermined interval in the longitudinal direction,
• wherein at least some of the fastening cells which are adjacent to each other in the longitudinal direction are separated from each other by an open space extending across the substrate in a lateral direction,
• wherein at least some of the plurality of breaks of the magnetic material are arranged to be aligned with the open spaces in the lateral direction,
• wherein a width of the open spaces in the longitudinal direction is set to be equal to a width of the at least some of the plurality of breaks of the magnetic material in the longitudinal direction.
