Flat pencil or pen that can be used as a bookmark- does such a thing exist successfully?
Recently, I was reading a book in which I needed to underline things, and I took it on some errands on the subway with me. I was using a regular mechanical pencil as a bookmark so I could underline as needed. However, the book wouldn't close properly, and the pencil kept sliding out of the book when it was in my bag, and it was annoying. Also, like many people, I sometimes like to carry a notebook and pen or pencil around with me, and have similar troubles then. It occurred to me that a flat or nearly flat writing instrument that could double as a bookmark would be an extremely useful thing. Google search produced these "flat sketching pencils"
, which still seem too thick. This comment in a previous thread
led to these pens
, which seem kind of cheap and poor quality, and also maybe too thick.
My question, then, is: Does a really good implementation of this idea already exist? Or are the above-linked examples the best we have for now? Has anyone encountered any interesting bookmark/pencil hybrids in the wild?
