I wish there was English subtitles….it looks very informative. Question. I did it this to myself, but my smile lines are different in length on some nails/on each nail, how do you make sure each nail has the same length? (How do you know how far down to dip on the first application ) And second question is , how do you fix up a nail where your white smile line didn’t take well (maybe it’s from me over filing it off)
