These are great! Super cute & STRONG! I received the green set.
I have very long & very thick hair, the kind that snaps pony tail elastics & requires an ubnoxious amount of bobby pins. I am in the process of growing out bangs, so these are a cute alternative to barrettes & headbands.
These bobby pins hold my hair away from my face & out of my eyes until I remove them. They hold my hair firmly, without digging or giving me a headache. These suckers are strong! That being said, I can see the frustration one might have using them.
I find that pulling them slightly open when sliding them in helps a great deal. The same goes for removing them. If I don't pull them open, they'll snag a bit at the ends.
I'm not sure that they're the kind you would use in a top-knot, at least with the amount of hair I'm dealing with, but I noticed that a thinner version is available on this site. I intend to purchase both the thick & thin types, in the "brights" & "flowers". Sure, they might be pricy, but they are both functional AND attractive.
