Covers most wooden pencils with standard sizes. Young writers who are just beginning to learn how to write letters will find the Tombow Yo-i Wooden Pencil Grip Aid ideal. This grip will help reinforce positive habits and teach the correct writing position for the hand when holding a pencil. The pencil should be held at a roughly 60-degree angle from the paper thanks to the grip, which is made to hold the middle of your thumb nail parallel to the paper. It even improves adult users' ergonomic comfort! Versions for both right and left hands are offered. Designed in Japan
