This is a great on-the-go pen for fans of the Hi-Tec-C who need a little more compact version. The Putimo comes out to about half the size of the regular Hi-Tec-C, while keeping the same barrel width and style. The lone addition the this pen is a removable loop you can use to attach to various things, such as a lanyard or clip. The tip is the same design and writes just as well as the full size model.
