What Makes Cosmo Air Light paper Special
The Tomoe River paper Challenger
When the formula change happened in Tomoe River paper in 2019, the fountain pen community began looking for alternatives. Cosmo Air Light has proved to become more than merely a fill-in the role: many reviews suggest Cosmo Air Light has improved upon the original.
Superior Performance Characteristics
According to fountain pen paper reviews, Cosmo Air Light excels particularly with sheen, shading, and smoothness – inks that don’t shade very much on Tomoe River shade nicely on CAL, and shimmering and sheening inks are enhanced with colors appearing brighter.
There is also zero feathering, and no bleed-through

Among the options currently being considered as alternatives to Tomoe River Paper, Cosmo Air Light has emerged as one of the best options available among the many options considered.
