As a teacher and a homemaker I have countless uses for the clear push pins. Once items are posted I am first assured that they will remain secure. This is of up-most importance around middle school students. I need not worry about students accidentally stepping on wayward push pins. Although push pins are available in a variety of color I generally prefer the clear ones since they are invisible and do not distract from the displayed items. In addition removing and reusing push pins are of importance to me as a cost-saving measure. Push pins go in easily and are removed easily. Busy teachers and homemakers appreciate items that respect their time and pocketbook.
I like the clear push pin because they don't make the rest of the display looked cluttered and distract the eye from what you want people to see. They are sturdy and don't bend easily.
