Mesh and Marble fidget - Pack of 3 (Boink)
It may not look like much, but this little fidget toy was an absolute hit with both the kids and the teachers that tested it for us. It is unobtrusive, silent and works very well in class to keep those idle hands busy while paying attention.
It is also another example of a new product that we have to hide in our house, otherwise every time we have friends over; they want some more of these fidgets.
It is a great support to have in the pencil case at school or in the pocket at home to just relieve some of the anxiety as it builds up.
They are available in a pack of 3 random colours.
