Green, Chinese made fuse for cross-matching 1/4-inch time fuse. This fuse is 1.5 mm diameter, high quality, and stiff, so that it's easy to cross-match with. Burns at about 1.9 seconds per inch. Gives and takes fire without priming. Inexpensive alternative to Thermalite or Manitor ignitor cords. Faster and easier than making black match.
