These pencil grips are made of soft and durable silicone material, which are safe and non-toxic, and have good elasticity, so they can be stretched and deformed repeatedly without losing their original shape. The pencil grips are designed with a unique wave pattern, which can effectively increase the friction between the pencil and the hand, and prevent the pencil from slipping. The surface of the pencil grips is smooth and comfortable, and does not stimulate the skin of the hands, making it suitable for long-term use. These pencil grips are suitable for both right-handed and left-handed people, and are very easy to install and use. They can be used not only on pencils, but also on pens, markers, crayons, paintbrushes, etc. They are very suitable for school, office, home, and other occasions.
