Designed for use on capacitive touchscreen devices, like iPads and most newer tablets and mobile phones, stylus pens can feel more natural for drawing and writing than using your finger, and helps keep your screen free from fingerprints.
Most of these have a stylus on one end for use on touchscreens and a pen on the other, making them ideal for everyday use. The Platinum Sensy has a stylus and three different colours of ballpoint pen - all in a slim barrel, in a choice of colours. The Sensy also has a very different stylus material, which is a lot more sensitive than most.
The majority of the stylus pen combinations here take standard refills, most commonly D1 multipen refills, giving you lots of choices for replacements.
