I just tried Incoco Dry Nail Polish Applique. It’s basically the same thing as Avon stick-on polish. I am having a really hard time; it won’t go on flatly. There are air pockets all through the edges. I’ve tried rubbing with both my fingertips and the white (slippery) side of the enclosed file. Also, when I tried to remove the ends (you have to file in a downward motion) it comes off in a mess and you just can’t file the tip smooth. Has anyone else tried these things and if so, do you have any tips?
