The Best
Silk wrap really is the best for mending fingernail AND toenails.  But for it to work its best you need a really good glue; Stick It is what I use.  The silk is quite sheer but strong (you can apply 2 layers, allowing proper drying time in between).  Once you cut it, it will fray a bit so make sure to cut a large enough piece.  Apply a drop of glue on the area to be mended & place the silk on top (its way easier to use tweezers for this); pat down with orange stick. Once dry trim away excess wrap with nail scissors & apply additional glue to cover.  Allow to dry completely before filing/buffing.  One thing to remember: do not touch the glue while it's wet...it's not called 'Stick It' for nothing!
