a beautiful, subtle shimmer when writing. Have had no issues with my primary use pen. No bleed through and very little feathering (in fact, I'd say only with applied, sustained pressure) on cheap paper. No issues whatsoever on my nice paper!
Dynamic ink! The black is very dark, with purple undertone. Shimmer and sheen make it elegant.
