Laser engraved mats have the design burned into the coconut fibers with a laser engraving machine (no paints are used), producing a dark brown tonal color. Although very crisp and clear, the darkened fibers will fade over time. These mats are great for special occasions or short term use. We highly recommend using the laser engraved mats in a well covered area, away from elements such as sun, rain and snow as much as possible. They will last much longer this way.
