Hi I wounder how you use CND Performance tips. I bought them when they just came to the market and I was at a training evning with the distrubutor here but she strugglet to show me how to use them. She said that you have to glue them in line with the free edge of the natural nail and you have to shape the free edge in the same shape as the line of the tip. And the tip has very deep curve. So I have never uset my tips becauce after what she said then the natural nail have to be quite long to put on the performance tip, and here if the customer comes in with so long nails they just want overlays on them. But I se here that many of you love to work with them. :green:
