Hairpins for Bun ROCST Bobby Pins Clips for Ballet Woman girl Hairdressing salon 12pcs

It looks like one end of a paper clip. These are the ones I use: https://a.co/d/08Uud3nT but you can buy cheaper ones that aren’t as strong or if you don’t have as much hair. I use the smaller ones for wigs and a box with a pound of them cost under $10. But I need like 10-12 to hold my bun vs. 5 of the ones linked above.
