It’S a pack of four toothbrushes and they were an add-on so the price was almost free. Couldn’t say no and. Hubby is happy as he is OCD about the monthly changing of the toothbrush. These are not his normal “hard” but I think they were Medium or Soft which is more of what your Dentist will tell you to use. They are rubber bristles as I recall and he said they really do the job and his teeth feel cleaner than his other brand. Happy husband teeth, happy wife with shiny husband teeth and good breath!
