This type of grip was used at a calligraphy class for a child who tends to press too hard when writing. It seems to have been easier to write with because it's soft and allows for more freedom than correction-focused grips. Why not give it a try? The set includes 5 pieces in random colors. You can add more for 40 yen each, so please comment before purchasing if you'd like to add more!
