Sharpie’s Liquid Pencil is an impressive feat of writing technologies that combines the best features of a pencil, pen, and permanent Sharpie marker into one product. The Liquid Pencil will go on sale in September, but Engadget’s got some hands-on time with this low-tech tech toy that packs in plenty of underlying technology research. When you write, Liquid Pencil uses liquid graphite so it writes like a pen with all the fluidity and ease, but you can also erase what you had just written like an ordinary pencil. Best of all, let it sit for 24-hours (according to the packaging), and your mark will be left–permanently–into history, unless you shred your manuscript.
Engadget found some things about the pencil, such as markings not erasing completely, and since you’re writing with a metal tip, you’ll have some indentation into the fibers of your paper. However, with those minor things aside, the popular gadget blog says “Still, it’s better than any erasable pen we’ve ever used, and it definitely writes like a decent clicky-pen, so we can’t fault it too much.”
