When I first received one of these pencils, my initial response was, great, there’s no eraser, thanks…I guess. Then this really nice person handing out treats gave me a couple more and explained why these pencils were cool and special. Instead of it having an eraser, there’s a plant seed with nutrients. So when you get down to the nub zone or that’s what I call it when I can’t realistically write any longer, you put the “eraser” side into the ground, water it and boom! A plant will grow from your former writing instrument.
