The mark for checking the loosening of bolts on the iron tower is called "Disappearing Line." It does not fade outdoors for about five years, allowing for visual inspection of bolt looseness. Our company, Okitsumo, has developed the "Disappearing Line," which excels in resistance to sunlight, rain, wind, and humidity (weather resistance), ensuring that the lines drawn do not fade outdoors and have minimal discoloration. ~ Have you ever faced the problem of letters written outdoors fading away? ~ With a typical marker, colors begin to fade in less than six months, but with the "Disappearing Line," the written characters remain intact for five years, with hardly any fading.
