BABYLISS!!!!!!!!!! their pro-ceramic curling tongs (white with black handle) are the best. I have them in 4 sizes,lol. It has 25 heat settings and has a green light indication to tell you the tong is heated up and ready to use.
I have bought A LOT of different tongs over the past 12 years and these are by far the best because they're durable and keep my hair curly thw whole day sometimes till the next day.
If you want a clipless tong..enzo milano are fabulous!!
