Fidgit spinner /roller

hotel magnum:
. . . some kids use these in schools to keep them in line apparently

Designed specifically for kids with Autism and ADHD, of which my grandson suffers from both, to act as a means of concentrating their minds hence stopping them from fidgeting. Thankfully he is at an age where his teachers understand the benefit he gains from it and therefore don’t allow these things in school apart from the kids they are designed for. Unfortunately elder Autism/ADHD children in higher schools don’t benefit from the understanding of less informed teachers and have had them banned from school en bloc, resulting in their anxieties increasing and their fidgeting returning.

These are not toys to those they were designed for.
