This paper shows off the sheen and shimmer in inks unlike any other paper can do. Fountain pen enthusiasts who favor shading ink, those that create subtle color gradations as ink is laid on the paper, will appreciate how the paper shows off subtle color variations. Sheening inks also perform well as pools of color will sit on the surface of the paper and when dry will create the reflective look so many fountain pen users love. It's important to be patient and let the paper fully dry to prevent smudging, especially when using sheening or metallic inks.
