Nail tape is used as an alternative to drawing straight lines with a brush. There are bad reviews about nail tape, stating that it peels off soon after applying. It is being used to tape a design, paint overtop with nail polish, and remove the tape instead of part of your mani. I use both ways. I found that if you press down on the ends before using topcoat, it stays on longer. Tape hanging off the ends of your nails speeds up the peeling process.
