I bought this because I feel like we have to have something to let people who need to know that our son is autistic. Yes he can talk but he doesn't respond as well as a normal person his age. especially if he thinks your mad at him or talking with authority. this tells those in authority that he is not going to answer the way they expect. I highly recommend this product. I use them on the zipper of the book bag, zipper on jacket, zipper on shoes anywhere I can find a place to put it.
