Zigzag Side On Bobby Pins
Bobby pins have two distinct sides: the wavy side and the straight side. Many people mistakenly place the straight side of the hairbrush against their scalp, although this is incorrect.

Due to the presence of magnetic iron oxide, they are more resistant to high-frequency electromagnetic interference.
