1/5/10pcs Magnetic Push Pins Strong Magnets for Whiteboard Refrigerator Office School Classroom

The handle is comfortable, the size is relatively small, but the power is strong - it exerts such force when tearing from a flat bare steel plate that, holding it by the handle with two fingers, it is barely possible to tear it off, unless you tilt it, then it moves.

Strong magnets. As described. Thank you Joom!
