When we take off the armor, we first use the abdomen of the nail drill bits to polish the middle position of the nail surface. The two sides can be adjusted into slightly fine teeth to polish, and the edge can be polished with its head.
When polishing, do not polish more than three times in the same place, or it will be a little hot. We only need to beat off the color glue, while the rest of the glue, we can directly use a sponge to bring down a few times, so not to hurt the nails.
By the way, ceramic nail bits can't be used to take off the metal. If a metal ornament is attached, remove it first and then remove it with a sander.
