Improve legibility of handwriting with our Weighted Pencil. The weight provides proprioceptive and tactile input for children who experience problems of dyspraxia or poor motor planning. The weight slides on and off easily, and can be placed at the finger grasp for a larger surface or higher on the pencil for a more normal grip. The slide-on weight is 0.03kg, an ideal weight for elementary ages through adults. Fits on #2 pencils and some disposable pens. Comes with (12) pencils, (2) grips, (5) weights and (10) rings.
