One day, a jeweler decided they'd like to touch their iPad, iPhone, iPod touch, and other touchscreen devices without the use of their finger. They tried the foam-tipped styluses, yes, and they did consider exercising their fingers to make them small enough for their needs, but it just wasn't good enough! That jeweler wanted something new. Thusly, they created the oStylus, a hinged "O" shape held at the end of a rod by hinges that allow it to stay flat to the screen, allowing you, the user, to be able to see everything you're drawing.
Made of stainless steel, titanium, and solid aluminum. Overall length: 17 cm (6 3/4"), handle length: 14 cm (5 1/2"), handle diameter: 6 mm (1/4"), contact O: 1 cm (7/16"), weight: 12 grams (0.4 oz). Designed mainly for drawing and painting on capacitive touchscreen devices, and there's a thin vinyl film applied to the contact pad so you don't have to worry about scratching up the screen.
