Review (5/5): I'm Impressed
These clips exceeded my expectations. They look delicate, but are very strong/sturdy. They're just the right size and hold my hair securely without any pinching or discomfort. I did a lot of physical activity earlier today (moving heavy boxes) and the clip didn't budge at all. They're also a nice weight--I have other large clips that are so heavy they hurt to wear for an extended period. Not these. I can wear one all day and barely feel it (like I did today).
I also think they're a very good value. There are four clips in the package for the same price (or less) than many other single clips this size sell for. They seem well-made, so I don't think I'll need to buy replacements anytime soon.
