I purchased a box of 40 sets of these pretty nails.
They do crack and split when you try to cut them.
To remove the well, I cut them first with sharp scissors, then with my electric file carbide bit carve out the rest.
You must "rough up" (with a hand file) ever so slightly (make sure you get the sides and edge) if you are going to coat them with gel or l/p.
The biggest problem that I've run into, using these, is separation, if the tip has been left too smooth before the overlay.
Could someone advise me how exactly you remove the well of a tip of using a file. Sorry to sound daft but I have only ever tried cutting a white tip with scissors and can't get an even smile line. I know with a natural tip the "smile" area will be blended anyway so that is not an issue.
Do you hold the file at a certain angle for example?
