Instabuy: rOtring 800+ rOtring has recently unveiled its new 800 that comes with a “+”. And this might be the most ingenious way to incorporate a rubber-thingy for tactile screens. The point of the mechanical pencil goes THROUGH the rubber. I find this as being not as goofy as most of the rubber-thingy on the top of the cap or the back of the pencil. This is just so elegant.
