Holds the main knot in place, whether you want smooth or messy buns
These are easy to use right out of the box.  Just wind your hair up in a bun-like shape and spin them in like you're opening a bottle of wine.  I have long medium-weight hair, so just about anything will hold it up, even a single bobby pin.  But what I like about these is that you can spin them in, making sure that you secure the lump to some strands of hair close to your head, and then use your fingers to loosen sections of your hair, so the bun's as big and messy as you want it to be, while still *feeling* like it's tight and secure and not going to come out.  It also makes the cutest tight-but-messy buns on people with thick shoulder-length hair.  My mom works on a farm and can use these and the wind will whip strands out, but the bun will still be intact at the end of the day.
