The White Gloss Laser (WS) is a glossy coated paper-based material and is not intended for outdoor use. A weatherproof option like our Weatherproof Polyester Laser (LP) or Weatherproof Vinyl Laser (LV) would be better options. However, the toners used in standard laser printers are not often UV resistant, so fading will occur in direct sunlight. https://www.onlinelabels.com/materials/polyester-laser-labels https://www.onlinelabels.com/materials/weatherproof-vinyl-laser
