Strong metal.
I have hair down to my butt and having it in a pony tail or a hair tie in general, all day puts strain on my head. I love picks, but my favorite wood one finally split and broke. So I bought this set. Love them!! They hold my hair in place and I can wear the bun loose or tight and the pick slips right in, holding my hair comfortably on my head. 3 gives me options of which one with what I'm wearing that day. But my go to one is the darker pick.
