Carole, our reading specialist was the person who introduced that Papermate pen to me. She would always leave a meeting making sure she had her pen. She said they had a strange predilection for disappearing.
Even here in Hawaii, they seem to wander away. I've now used a magic marker and written my name on it and that seems to have worked. They may wander away, but eventually they come back to me. I like this pen because it doesn't have a cap that can be left behind somewhere and it doesn't feel quite as hard in my hand. For that same reason, the Bic Grip pencil just feels good to me.
I've been using these same pens now for over 8 years. I just buy refills all the time. Do you have a favorite writing tool?
