Mark patterns on dark surfaces with the FastCap Long Nosed Pattern Marker. The metallic silver color shows up clearly on black foam and darker woods like walnut or ebony. This pattern marker makes tracing around items, marking inside holes and along walls easy. The long thin nose of the marker comes in close to the item. The soft felt-like tip dispenses the colour with little pressure. The broad tipped end produces a thicker mark for general use. The silver ink is permanent and waterproof.
