Abstract
A magnetic fixing member is produced by fitting a metal plate having suitable magnetism to one of the surfaces of a thin sheet-like ferrite type anisotropic rubber manget. The size of the fixing member is determined so as to be fitted into a gap defined between a paper package box to be held by the force of magnetic attraction of the rubber magnet and the contents of the paper package box. The rubber magnet sheet has at least two poles magnetized on one of its planes.
