These Breeze Thru Double Prong Pin Curl Root Clips are just like the pin curl clips I received in my cosmetology kit over 30 years ago. I'm not sure how it works now, but back then, you had to do pin curls, a lot. It was also part of your test in order to get your license. I've had my first clips for over 30 years, but they had finally dwindled down to only a handful. I was so happy when these crossed my path!Though I don't do traditional pin curls anymore, I will be using these for styling and restyling my wigs. They will be great for holding finger rolled curls, so that I don't have to add heat to either my synthetic or human hair wigs. They will work just the same with your own hair, keeping damage to a minimum.They seem to be the same quality as my original ones, so I'm expecting them to last till the end of my life. These are really nice, versatile clips, and I would definitely recommend them!
