This patented, ergonomic pencil grip was designed and tested by pediatric occupational therapists specializing in handwriting. With consistent use, the Grotto Grip® trains the hand to form a proper grasp. Other leading ergonomic pencil grips may feel comfortable but they support the hand at the finger joints encouraging whole arm and hand movements; actually encouraging a static grasp pattern rather than the use of dynamic finger movements. Dynamic finger movements lead to more precision and increased writing speed. The Grotto Grip® actually activates the muscles in the palm of your hand to allow dynamic finger movements. The Grotto Grip® was designed with optimal firmness as recommended by occupational therapists to provide sufficient feedback to the fingers to maintain a proper grasp while writing. Grips that are too soft, lack finger guards or place the fingers too far from the pencil point may reinforce improper grasp habits. The Grotto Grip’s® unique design places the hand and fingers in a position which shifts the support to the palm of the hand and facilitates the user to hold the wrist in an extended position; the proper way to hold a writing utensil. For both left & right-handed writers. Non Toxic & Latex Free. Assorted colors. Each pack includes 36 grips.
