Align Blade Head: Ensure the blade head is properly aligned with the top of the razor handle, with the blades facing away from the razor and the grey clips facing towards the handle. 

Attach Blade Head: 

• Holding the FFS handle in one hand and the blade head in the other, position the blade head in front of the handle. 
• Press the blade head firmly into the handle, making sure the blade clips slide into the designated slots on the handle. 
• Apply pressure until you hear a distinct click, indicating that the blade head is securely attached to the handle. 

Confirm Attachment: After hearing the click, gently tug on the blade head to confirm that it is securely attached to the razor handle. If properly attached, the blade head should not easily come off. 

Remove Blade Head: 

• Locate the button near the top of the razor handle  
• Press and slide the button upwards, and the blade should detach easily. 
• Continue holding the button until the blade head is detached from the handle. 

Store Properly: When not in use, store the FFS handle and blade heads in a safe and dry place to prevent damage and ensure longevity
