Sakura Souffle is a very exciting gel pencil that leaves a slightly higher drop line on the surface and is especially good for various creative projects. Souffled can be used on a variety of materials, including paper, glass, plastic, and metal, as well as ink on dark surfaces.
Yellow tones are very intense, almost neon.
P.S When using Souffled, take some time and write-draw more slowly so that the thick gel ink can come out enough. Let your work dry - this can sometimes take as little as 10 minutes.
