I looked at my nails and then wondered if there was a depiction that could be connected to the brain’s idea as a depicting tool for nails in the future.
This tool would solve the complex manual painting process, and the painter would be able to paint the nail directly from the brain’s idea, which would be the most direct art tool.
This tool can solve the lack of workforce because it takes a long time to make a beautiful nail, and a nail artist must know how to paint to create a good style.
