Archival Inks are waterproof, acid-free dye inks featuring classic Distress colors in the same fade resistant formula used in Ranger Archival Ink. Archival Inks are permanent on many surfaces and provide long lasting detailed stamping results that won't bleed when used with water-based inks, markers, acrylic paint, and watercolors. Ink pads can be easily re-inked with the coordinating Tim Holtz Distress Archival Ink Re-inkers. Archival Ink Pad Stack features four 2 x 3 inch standard ink pads including Vintage Photo, Ground Espresso, Hickory Smoke, and Black Soot.
