Tim Holtz Distress Inks are a collection of acid-free, non-toxic, fade resistant, water-based dye inks. Theyare perfect for the new vintage, stained, aged effect crafters are creating in their altered books, scrapbook pages, cards and paper craft projects. Tim selected the colors and helped develop these inks to produce a realistic, weathered look on paper, photos and decorative fibers. All the Distress Inks afford added versatility when photo tinting and color layering with the original, award winning tones. The " x " pads are made with a higher raised felt for easier use with direct to paper techniques. Acid free.
