Series - Telescopic Stylus from Zebra . Telescopic Stylus are ballpoint pens that easily go from a folded length of 97 mm to a full length of 130 mm. Just by pulling out the pen. The pen has a touchscreen function on the back, great for fumbling fingers on mobile phones during the winter. Available in four nice colors!
If you want a small pen that doesn't necessarily need to be transformed into a long one, then we recommend that you also take a look at Leuchtturms1917 pens Drehgriffel.
However, we do not have any other pens with touchscreen function.
