The Versafine ink pad from Japanese brand, Tsukineko, is made with an oil-based pigment ink, meaning it is waterproof and won't smear. The ink won't bleed into paper, making it ideal for stamps with fine details. Perfect for using in your watercolour artwork or with markers. Best used with matte cardstock, it dries in under 5 seconds on uncoated paper. It is also light-fast, acid-free, and fade-resistant, making it archival quality. Versafine ink pads last 3-5 times longer than other ink pads. The supermoist ink will not dry out in the pad, even if left uncovered for extended periods.
