Fits. Y OralB
The original hard plastic travel case for my toothbrush cracked during a flight.  (My fault as I had stuffed it near the outside of the bag and was crushed.). This case is a “softer” plastic and has more give.  Cleans up easily and has a plastic cradle so the toothbrush and brush don’t move.  Check your model number to make sure it will fit.
