Review (1/5): Weak.
They are for clamping down really hard on extension beads. But if you clamp down really hard -which you have to do if you want your hair extensions to STAY IN, AND NOT JUST SLIP OUT ALL THE TIME- the pliars separate! If you just clamp down hard a few times to close the beads, the pliars get messed up and there's a gap when you clamp down... Like, the ends do not meet completely! Ugh, very frustrating. This has happened with 3 pair, different sellers. So I finally discovered LINESMAN PLIARS! Just like, at the hardware store. These are the perfect hair extension pliars! You can squeeze as hard as you want... Hundreds of beads later, and they are still perfect!
