Hairdressers - what are these called?

[AnxiousAnnabel]

These hairpins are amazing for my thick hair, but searching for 'thick hairpins' isn't bringing them up online.

I often see them used in tutorials when temporarily holding different stages of up-do's in place? Is there a specific name for them?

Thanks @MrsPelligrinoPetrichor , but the ones I'm looking for are straighter and more robust than the wavy bobby pins you normally see. They're also more difficult to bend (my hair puts up quite the fight against some of the flimsier versions!)

They used to be used for holding rollers instead of plastic pins. You can also find them called straight hair pins.
