In my Influenster Beauty Blogger Fall 2012 VoxBox, I was sent a set of 2 Spin Pins from Goody. These pins were advertised to be the only pins you would need for their hairstyles. To be perfectly honest, though, I had to use multiple booby pins to help keep my hair in place. I'm not sure if it's just my hair or what, but I was a little bit disappointed. I can use them still, but I will just have to make sure I also have booby pins on hand.
A 2-pack of Spin Pins retails for $7.29 at Walmart. I don't think I would have paid that price for these pins, myself.
*Please Note: I received this product entirely free of charge from Influenster.*
UPDATE (Nov 25): The second photo is another style that I tried today, a double knot. I had much better luck with this, and both buns held through the day with just one spin pin each and some hairspray. Much better!
