Boinks Fidgets are a great tool for children and adults who need something to occupy their hands. Fidgets feature a marble inside a tube of woven plastic - simply slide the marble back and forth to keep your hands "quiet" and to avoid other distracting or destructive fidgeting behaviors. Fidgets can be used to relieve stress, develop fine motor skills, and for therapy for those with ADD, ADHD, dementia and more. 3 fidgets per package, measure approximately 3-1/4" long. Colors vary.
