Please note this item does not fit the Mach 3, Fusion or Gillette Sensor handles. Directions ---------- To install the Taconic Shave razor blade cartridge, first ensure the razor handle is clean and dry. For pivot-style handles, like the Trac 2, open the cartridge door at the bottom of the handle by rotating it away from the razor head. Slide the new cartridge onto the exposed pegs until it clicks into place. For clip-style handles, like the Atra, Contour, and Vector, align the cartridge's slots with the handle's pins and gently press the cartridge down until it clicks. Before shaving, rinse the razor head and blades with warm water, apply shaving cream or gel, and shave in the direction of hair growth. After shaving, rinse the razor head and blades thoroughly, tap off excess water, and store the razor in a dry place. For maintenance, clean the razor head and blades regularly and replace the cartridge when needed for optimal performance and skin comfort.
