These are replacement heads for the Closeup Sonic Expert electric toothbrush; a powered handle is not included. The reverse pack identifies 0.1mm ultra-thin bristles. Colour refers to the brush heads, rather than the outer carton. Packaging may vary. Supplier instructions for use with the compatible powered handle: 1. Connect brush head and ensure that it is secure. 2. Apply toothpaste to brush head. To prevent splashing from toothpaste, wet the brush head and put it in your mouth before turning on the toothbrush. 3. The on/off button can be used to select the preferred mode. It must be pressed within 3 seconds of start to change mode. 4. Select one of the 3 modes (Whitening, Clean or Sensitive). 5. Focus on one quarter of your mouth for 30 seconds. Gently brush each tooth, focusing on the chewing surface, back surfaces and front surfaces. 6. When the auto-reminder briefly pauses every 30 seconds, move into the next section of the mouth. The toothbrush will shut off on its own after 2 minutes. Precautions: For external use only Care and replacement: The package recommends changing the brush head every 3 months, or sooner if the bristles become frayed with use.
