If your child constantly fidgets in his or her desk, or at home while doing homework, the Desk Buddy Sensory Bar is for them. A team of an Occupational Therapist, School Teacher and product engineers combined efforts to create this product for both classroom and home use. For children who are constantly looking for different textures to touch or 'fidget' with, the Desk Buddy is both practical and socially acceptable in a school setting. It is simply a ruler sitting on their desk. The desk buddy is constructed from an FDA approved material so its even safe to chew on if the need was to arise. Completely dishwasher safe, and naturally bacteria resistant.
