Good for my Purposes
This is a set of 3 toothbrushes each with a small snap on cover for the head. Please read the description and note that it says "NANO" which means small. I did not read that. I have attached photos so you can see that the head of this brush is much smaller in length and width than a standard toothbrush. I placed a quarter next to the heads so you can have a point of reference.  I am using this for brushing a dog's teeth and it is a smaller dog so they work great. They would serve as a brush for a child but I would not recommend it for an adult unless you really do not want it to cover much surface area at a time. The bristles are silicone and as such are softer than nylon bristles but do not misconstrue this that they will be like silk threads...they have a soft rubbery feel versus a traditional toothbrush.
