Unique black notebook paper with light white lines that provides excellent reverse contrast. This phenomenal paper reduces the light that bounces off traditional white notebook paper and is more comfortable visually for many individuals who have visual sensitivity or visual processing differences. The perfect writing tool to pair with gel pens, metallic markers, fluoresent markers, or our white charcoal pencils (which are somewhat similar to chalk and can smear). Comes in 150 sheet packages. AWESOME!
