Review on 5 Pack Stylus Pens for Touch Screens - Capacitive Sensitivity 2 in 1 Stylish Pencils - Compatible with iPad, iPhone, Tablets & Universal Touch Devices (Red+Purple+Green+Gold+Silver) by Jeremy Reddick

Edit: I downgraded my rating from 3 to 1 star . Only 3 disk tips worked. I had to throw the rest away. You can screw on the cap at both ends. I switched it over to close the end with rubber tip. When I tried to remove the cap the tip in the cap came loose and now I can't separate it. It would be better if the cap just snapped on and didn't have threads.
