LaserBright is a brand of our laser engraving Aluminum sheet (0.2~1.0mm). When you use a CO2 laser to engrave, it'll change to another color. Now we
  have 23 different colors & finishes to choose from. This product has metallic surface and texture, which is obviously different from plastic materials. It can
  be used outdoors. At present, we are also the only manufacturer in China that produces this kind of product.
