Rit DyeMore Dye is specifically formulated for dying synthetic fabrics and fabric blends such as polyester, acrylic, nylon, and acetate. It offers a colorful kick, great for personalizing garments, household items, and decor. It even works with 3D printed items, wigs, and most plastics. This non-toxic dye is to be used with a stove-top method of dying rather than a washing machine to ensure color penetration through high heat on the material you are coloring. Use it to give your new creations or old items a stylish pop of color and pizzazz! Bottle contains 7 fluid ounces of dye.
