Abstract: A portable, credit card size, holder for keys and the like comprises a laminated assembly having two plies of thermoplastic film sealed together at their marginal edges; and in its preferred embodiment, having a flat card-like insert, slightly smaller in area than the plies of film, having a main body and two spaced apart end portions on one face of the main body, the insert being sandwiched between the plies of film; the ply of film contiguous to said end portions having a pair of slits therein, aligned respectively with the free edges of the end portions, thereby forming two end pockets accommodating insertion of keys for secure, but removable retention of the keys by the laminated assembly.
