Roll it between palms for a scratchy/tickly sensation.
This helps stabilise the core for wriggly bodies & those that have trouble sitting still. Also can be rolled in fingers or spun.
The Kaiko Fidget range is incredibly popular for older children, teenagers and adults. They are simple in design using stainless steel metal parts which give them a funky look and feel and also mean they do not break easily.
