15Those Multi-Color Pens
The worst part of it was that all the colors were on springs, so if you messed with it too much the springs would mess up or you might get two colors going forward and jam up. There was always that one kid who knew how to fix them in
school though, so you had to rely on him. However, he always had a sea of other pens to work with. So this bulky thing was seldom worth having. But we ALL had one, but very few kids would want one today.
