Wrinkle tool #4 is a single sided tool with 3 prongs (.047 wire). You can quickly add lots of wrinkles to larger areas by dragging the end back and forth across the area to be textured. It is also recommended to sand the tips to your liking. You can lay a piece of plastic wrap over the area to be textured and drag the tips across the surface for a softer look. The overall tool length is 8.25″ the tubing is 5″. This is a much heavier wire and is very stiff.
