Nano Product: Keratin Ink

Using genetically modified bacteria, Keratin Ink turns your fingernail clippings into a highly personal ink for writing and drawing. The bacteria transform the keratin in your hair and nails into a dark brown pigment. No need to worry about the microorganisms escaping: Each Keratin Ink well keeps the bacteria safely sealed away. A great gift for the eco-conscious recycler in your life.
