These replacement cutters are compatible with the Gamma+ and StyleCraft Uno shavers only. Superior ultra-thin stainless steel cutters with hypo-allergenic properties - 1x FORGED for increased power and 1x CRUNCHY for smoother shaving with more audible cutting. HOW TO REPLACE CUTTERS - Make sure your device is in the OFF position. Firmly grasp both sides of the foil head and pull away from the device to remove the head. Pull up on the existing cutter blade to pull out of the socket. Line up the new cutter with the socket and insert until it snaps into place. Replace the foil head onto the device. Replacing your blades every 3-6 months gives you a better, closer shave with fewer nicks and cuts to the skin. For best operation, clean your cutters regularly or daily depending on usage by rinsing with warm water and gently brushing with a small soft bristle brush or blow out carefully with compressed air to remove debris. Make sure that all components are completely dry before placing it back onto the shaver.

Ideal for sensitive skin.
