A protective packaging device for a shock sensitive product being shipped or stored in a rectilinear outer packaging container comprises a product receiving cavity having product contacting walls and a product supporting platform. A base portion located below the product receiving cavity has two pairs of deflection elements extending diagonally away from the corners of the cavity towards external outer packaging container contacting corners, and bottom outer packaging container contacting lips at the bottom of the base portion. The distances between adjacent pairs of outer packaging container contacting corners are substantially equal to the internal distances between adjacent pairs of corners of the outer packaging container. The deflection elements are adapted to flex away one from another, and the bottom outer packaging container contacting lips are adapted to spread away from one another, under shock loading conditions. Thus, shock protection is provided in three mutually perpendicular directions.
