Adding a straw to a notebook

I am not sure if there are larger straws out there but I tried three different kinds all with the same results. A pen or pencil do not fit inside straws so this pin does not work.  It is a good idea if the pens and pencils would fit in the straw but the straw is much smaller than the pen/pencil.
