I have two of these brushes. I received them in a couple of monthly subscription boxes. I’m not sure what website they were ordered from, because the items are picked out by professionally trained occupational therapists before they go into the boxes. I have one of these brushes in my backpack for travel. And I have one that I use at home. I like to use them for emotional regulation, and I also like to use them as a fidget. Fun fact, this brush also helps me when I’m dysregulated from trauma as well as autism.
