hi, i think u might mean the inverted moulds, if you do the nail tech at our salon uses them and they are fantastic! they do cut time and despite the opinion of 'they are just stick on nails', they give the most natural finish and they are the best set ive ever had. i work in northwich, which is where the only supplier is, but they are setting a website up v soon which you can buy them on!
Thx for answering. I don,t mean the molds. What i am talking about is a technique without the use of any mould or extra tool. It,s basically doing your pink first in zone 3 and 2 and sort of shape your smile line with the pink when you push it in place. Then you just put the white straight against it and you have razor sharp smile lines.
