Perfect Medium Pens, designed for use with Perfect Pearls Pigments and embossing powders, add drama to your artwork. Perfect medium develops an acid-free bond with Perfect Pearls, allowing the pigments to set without the use of a fixative. The pens are a great choice for scrapbookers, rubber stampers, calligraphers, book makers, journalists, and paper crafters. The Perfect Medium Pen set contains two pens, each with a distinct nib. One pen has a fine bullet tip that's great for writing, printing, drawing, and making ruler lines. The other pen has a versatile brush tip that's perfect for painting in small or large areas and for creating unique design elements.
