If you're suffering anxiety or if you're a nail biter / skin picker, these fidget tools are by far the best to keep you sane or to stop you from biting or picking your nails.
This is a great fidget toy, there are so many options for buttons, switches, spinners etc. Great for also keeping in one hand whilst working etc.
