Our company uses these clips for every install we do. These are hands down the best you'll find.
I have bought these over the phone which Christmas Light Source is perfect to deal with on the phone cause when I placed my order the wonderful lady put me on hold to go ask a few questions and get me answers to every one of my questions. I use these clips by twisting the ends to act like tweezers to hold Mini Lights all the way around my house, windows, porch post, lamp post even my garage door. I will NOT deal with anyone else but Christmas Light Source from here on out and when it comes time to transfer to LED lights which will be this year, lol, I will be placing my order on the phone just so I can deal with the A+ Customer service they have shown to me. Can't wait.
