With Lexmarks return policy you can easily send your used cartridges back to be reused. This means that not only are you doing your part for the environment, but you also save the bother of disposing of the cartridges yourself. Just because these are environmentally friendly doesnt mean that they skimp on quality, providing you with lines that are sharp and images that are defined. The Lexmark 105XL Black Inkjet Cartridge can provide you with both stark, bold tones and subtle, gradated shades.
