This Jumbo pencil grip provides much comfort and support up to the joints of the fingers. Its ergonomic design allows correct finger positioning of a dynamic tripod grasp and therefore promotes the pencil control and reduces fatigue of the hand during handwriting.
 
Basically, insert the pencil into the hole with the bulkier side on the top. Place the pad of the thumb on the side marked ‘R’ for people who are right handed and ‘L’ for those who are left handed.
