Exquisite Rhinestone Design Each of the three hair clips come set with geometrically cut rhinestones that fully cover the hair clips to elegantly reflect light creating a beautiful and elegant shine. Durable Material Made of good grade alloy material, these hair pins are sturdy & are built to last. The shining rhinestones are stuck using strong glue & thus will not fall off over time. Spring Clip Closure The clips can hold the hair in place firmly through out the day without loosening or pulling on the hair, thanks to its spring clip closure which also makes it easy to open & close the clips.
