Found out about these on one of my favorite black hair care forums: LHCF
They looked really cool and after some naturals chimed in on the thread saying it didn't get tangled in their kinks, koils n kurls; then I was really down to try them. I went to my local Wal-Mart for $6. You get 2 in the pack.
The spin pin is supposed to do the job of "20 bobby pins". I don't know about 20 but it definitely does the job of multiple bobby pins. Like the kinky kurly posters stated, they also did not get caught or tangled in my hair. #score They're super easy to use; just like the name suggests, you "spin"/twist them in. Turn them clockwise to insert into hair and twist counter clockwise when taking them out.
I only used 2 spin pins and the bun was secure, a loose bun, but secure none the less.
