Zigzag Side On Bobby Pins
Bobby pins have two sides: the wavy one and the straight one. Usually, people use them in a way that wavy pattern faces the scalp. While that does look cooler, this is not the only thing it does! The pattern keeps it secure in the spot and keeps it in the spot the whole day. It’s easier to hold onto hair like this.
Cable Cord Cylinders
We do not know about you, but we used to wonder what those cylinder-like lumps towards the end of cords are and do. If you must know, they are called ferrite chokes or cores! They come with magnetic iron oxide, which prevents high-frequency electromagnetic interference. Your call might get interrupted by weird noises if your phone is too close to the speaker. These cylinders actually prevent these things.
