This is a charging glass cup for Philips Sonicare toothbrushes. I was using the HX9308 electric toothbrush. You can charge the toothbrush simply by placing the glass cup on the charging base and putting the electric toothbrush inside. It can also be used as a cup for rinsing your mouth. There are no scratches or cracks to my untrained eye. I am selling it because I bought a new electric toothbrush. Please understand that this item has been stored by a private individual. Thank you.
