The Tsukineko VersaFine ink has been specially designed for precise stamping. It is recommended to use this ink in combination with stamps. Tsukineko VersaFine is an oil-based pigment ink that dries directly on paper surfaces. Tsukineko VersaFine lasts significantly longer than other stamp pads, so no refills are necessary. The lid is movable and can be folded down to facilitate inking. The ink does not bleed through the sides of the stamp block. The boxes are stackable.
