• a solid erodable body of a shaving aid material consisting essentially of a soap-type material, wherein the body includes a base surface and a contact surface;
• a first aperture disposed in the contact surface and extending between the base surface and the contact surface, wherein the first aperture defines a centerline and is sized to encircle a razor cartridge of the razor assembly;
• and
• a base partially or completely embedded in the erodable body adjacent the base surface;
• wherein the base includes a first surface and a second aperture sized to receive the razor cartridge;
• and
• wherein the base further includes one or more projections attached to the base and disposed on opposed sides of the second aperture having shaving aid material solidification apertures extending in a direction parallel to the centerline of the first aperture through the projections, a plurality of tabs that extend laterally out from the base to locate the shaving aid cartridge within packaging;
• and wherein no part of the base extends from the first surface to the contact surface between the solid erodable body and the first aperture;
• and
• wherein the soap-type material passes through and beyond the shaving aid material solidification apertures to define a continuous path around a portion of the projection to secure the solid erodable body to the base;
