Many people chew on their pencils, either out of nervousness or boredom. But pencils taste like wood (or rubber if you’re chewing the eraser). So if you’re going to be chewing on your pencil, why not make the end of it a lollipop so at least you’d have a tasty treat when you’re not writing. It makes a whole lot of sense I guess. The only problem I see with these lollipop pencils is that you can never put them down unless you want your pencil to stick to the desk (or worse- your pocket).
