Efficient Drawing Pin / drawing pin

Efficient Drawing Pin
Efficient Drawing Pin

We can hardly handle both papers and drawing pins when we pin some paper on the board, and normally one side of paper is pinned up, while the other side falling over. This efficient drawing pin can solve this problem nicely with its two pins. The paper can be pinned up steady with only one drawing pin.
