Of course you don't need a stylus to operate your NOOK, but consider the advantages, such as superior accuracy and the absence of unsightly finger smudges. The Vara's specialized capacitive tip glides smoothly across the screen, mimicking the pressure of your finger, while the ergonomic design and soft-touch coating ensure a reliable and comfortable grip. But that's only half the story. The opposite end of the stylus incorporates a high-quality roller-tip pen that writes cleanly and effortlessly on paper. Simply remove the protective cap, and you're ready to write. An integrated clip allows you to attach the stylus to your NOOK cover, so you don't have to worry about misplacing it. Length: 5.75 inch, Molded plastic body, Incorporates capacitive rubber tip and roller-tip pen. Suitable for NOOK HD, NOOK HD+, and NOOK Simple Touch only.
