YINQAG 10 PCS Spiral Bobby Hair Pins，Twist Screw Hair Pins，Hair Pin Spin，Hair Bun Coil Clip for DIY Hair Style (Black)

These are sturdier and of higher quality than I expected. I've got waist-length hair, so creating an updo with traditional bobby-pins can be a real bobby-pain. (See what I did there?) One of these replaces many of those, they stay where I put 'em, and they are very easy to use. Just keep Ghostbusters rules in mind: don't cross the streams. Or, in this case, the twisted metal bits. They can get kind of stuck together if you cross them, and getting them un-stuck from each other - and your hair - can require time, patience, and an extensive vocabulary of creative curse words. It's quite the commitment and best avoided.That potentiality aside, if you have hair and you like to put it up, give these a try.
