Uni Stylus Pen: Equipped with a special fiber "Ag-fiber nib" for GIGA schools, a lightweight touch that mimics the shape of a pencil shaft, and a highly responsive Giga school stylus pen (Product Features) ■ Uses a special fiber "Ag-fiber nib" that has been treated with a silver coating on the nib of a highly reaction. When the "Ag-fiber nib" touches the screen, the special conductive fibers expand to ensure the contact area. This allows for a responsive and stable writing without crushing the nib. ■ Replaceable tip tip tip is consumable, but the Ag fiber nib can be removed and replaced from the main unit, so you can use it economically. It is time to replace the stylus pen when it becomes poor reactive, or the color of the pen turns brown. ■ Comes with 1 extra touch nib and a spare "replacement nib" is set inside the nib cap, so you can quickly replace the nib when it wears out. After replacing the "replacement nib" inside the nib cap, please store the spare touch tip storage part (sold separately) in order to protect the touch nib. Please close the cap after use. The same hexagonal barrel as the easy to hold pencil. It is designed to be used with a sturdy grip. The shaft color is the same as our premium pencil "uni" paint that shows the image of the pencils with a luxurious "uni" paint that is made in Japan. About the compatibility of the nib, the touch tip of this product and the Jetstream stylus are common specifications.
