Review (5/5): Holds well!
These pins hold great! They are made of a thin metal and I was worried that they might bend since my hair is really thick and unruly, but they hold it together nicely! I haven't had any pins bend yet, and I've used them every day for a month. The ends are slightly rounded so as to not be sharp, but they are still a bit pointy. The pins are completely smooth, and there is nothing for hair to get caught on. The colors are super cute too!
Overall these are wonderful chignon pins and a great way to put hair in a bun without damaging the hair. They work just as well as hair sticks without being quite so big. Just a little bit of the pin sticks out from the bun if you're making a regular sized bun, and it isn't too large for smaller double-buns either. If you have a TON of hair it may not stick out as much, but I think it'll still do a decent job at holding the hair in place if you put it in right.
