Ooh, this looks interesting: the Sharpie liquid pencil. Made from “liquid graphite” and introduced on the company blog earlier this month, it’s been making its way through the Internet at a fairly rapid clip.
The idea, one gathers, is that it’s initially erasable, then becomes permanent with time. How much time is unclear; some sources are saying 24 hours, others give you up to three days. (“But unlike a Sharpie permanent marker, you will always be able to erase it to some degree,” according to a company update.)
The liquid pencil will be available in the US in September, though there’ve already been a couple of sightings at Office Depot. Have you tried it?
