[Edge of the nail does not have enough length]

Clips may hurt the skin if edge of the nail doesn’t have enough length. We recommend keeping the edge of the nail around 2.5mm, but if the edge is at least 1mm at both side of the nail, the special approach is available.
Attach only 2 clips upside down on the both side of the nail
*Because the wire comes to the upper side of the nail in this approach, it may become easier to get caught and come off in daily life.
In order to prevent those cases, we recommend to coat about 5mm from the tip of the nail with gel adhesive glue to cover clips. If it still seems to get caught, please protect it with tape such as plaster.
