Review (3/5): Good value, except some of the pins aren't worth it.
These pins are a mixed bag. The double-tined pins are the best. Those pins are long and strong, with a touch of flexibility. One of these keeps my hair up and out of the way without snagging or pulling.
The single pins, are also strong and flexible...just not very long. If you've got lots of thick curly hair as I do, it will take several strategically placed pins to keep things together.
Finally some of the single pins have a raised design that runs the full length of the too-short pin. The problem is that the raised design catches at my hair and pulls. You might get the pin in, and enough of them to hold your hair up, but it may come loose, carrying part of your hair with it, making it harder to reinsert. Intentionally pulling these pins out is just as bad.
So if you are fine paying the total price for the double-tined pins in the collection, it's all good. If not, and your hair is fine with the shorter smooth pins, it's still good.
I do not recommend using the pins with the full length design. Ouch.
