If you’re into writing the “old-fashioned” way - that is with a pen and paper - then you’re probably already acquainted with Sharpie, the company that brought us those markers and pens that come in all shapes, colors and sizes. Their latest offering - called the Sharpie Liquid Pencil - is really quite unique. It writes like a pen but can be erased like a pencil and it becomes as permanent as a permanent marker in three days.
The secret to the Sharpie Liquid Pencil is that it contains liquid graphite, which enables you to write as cleanly and smoothly as with a pen. However, if you have second thoughts, you can erase the “ink” just as you would if your words were written in pencil. But beware – you only get three days to do so, before the ink becomes permanent.
According to the Sharpie blog the Liquid Pencil will be available in September, 2010 – which is good news if you're prone to changing your mind! And if you can't wait, there's already a version at Office Depot for US$4.99 which includes two pens and four erasers.
