Abstract
A closure for a flexible case such as a brief case, purse or the like, wherein opposing flexible magnetic plastic strips border the opening or mouth of the case, the opposing strips being arranged to be of opposite polarity to develop an attraction force between them. Opposed opening tabs may be provided in such manner as to facilitate opening of the case without tendency to inadvertently remove the strip from its location of attachment, while corner clips effectively reinforce the upper corners of the case.
