A shaving blade unit comprising: a housing having a bottom surface and a top surface defining a pocket and a pair of elongated spaced apart apertures (64, 66) positioned within the pocket between a front wall of the housing and an elastomeric member, and the elongated spaced apart apertures (64, 66) extending from the top surface to the bottom surface; at least one blade mounted to the housing, the blade having a blade edge extending generally parallel to the pair of apertures (64, 66); a solid polymeric lubrication member having an upper skin contact surface and an opposing base, the solid polymeric lubrication member being pressed into the pocket; a pair protrusions (54, 56) extending from the base, each protrusion (54, 56) having an enlarged distal end (58, 59), the enlarged distal ends of the protrusions each having a dimension greater than a dimension of the corresponding aperture (64,66), the protrusions (54, 56) being pressed into the corresponding apertures (64, 66) of the housing with corresponding angles of the enlarged distal ends (58, 59) of the protrusions (54, 56), and the apertures (64, 66) of the housing facilitating the front wall of the housing to deform, wherein the solid polymeric lubrication member is positioned within the pocket defined by the front wall and a pair of internal sidewalls (70, 72) of the housing, the pair of sidewalls (70, 72) and the front wall of the housing and the elastomeric member surrounding the solid polymeric lubrication member, and wherein inserting the protrusion into the corresponding aperture deflects the front wall of the housing and each of the enlarged distal ends (58, 59) engage the bottom surface of the housing, and the solid polymeric lubrication member and the enlarged distal ends are molded from a water soluble polymer. a housing having a bottom surface and a top surface defining a pocket and a pair of elongated spaced apart apertures (64, 66) positioned within the pocket between a front wall of the housing and an elastomeric member, and the elongated spaced apart apertures (64, 66) extending from the top surface to the bottom surface; at least one blade mounted to the housing, the blade having a blade edge extending generally parallel to the pair of apertures (64, 66); a solid polymeric lubrication member having an upper skin contact surface and an opposing base, the solid polymeric lubrication member being pressed into the pocket; a pair protrusions (54, 56) extending from the base, each protrusion (54, 56) having an enlarged distal end (58, 59), the enlarged distal ends of the protrusions each having a dimension greater than a dimension of the corresponding aperture (64,66), the protrusions (54, 56) being pressed into the corresponding apertures (64, 66) of the housing with corresponding angles of the enlarged distal ends (58, 59) of the protrusions (54, 56), and the apertures (64, 66) of the housing facilitating the front wall of the housing to deform, wherein the solid polymeric lubrication member is positioned within the pocket defined by the front wall and a pair of internal sidewalls (70, 72) of the housing, the pair of sidewalls (70, 72) and the front wall of the housing and the elastomeric member surrounding the solid polymeric lubrication member, and wherein inserting the protrusion into the corresponding aperture deflects the front wall of the housing and each of the enlarged distal ends (58, 59) engage the bottom surface of the housing, and the solid polymeric lubrication member and the enlarged distal ends are molded from a water soluble polymer.
