Green Onion Anti Glare Screen Protector keep your cell phone screen safe and scratch free, while giving your screen an anti-glare finish. These hard-coated and scratch-resistant PET films attach with silicone glue, making installation simple. This adds no bulk to your phone, but keeps its screen safe and clean of scratches or abrasions. The built-in anti-glare filter reduces the reflectivity of your screen, greatly improving clarity in bright lighting conditions. This turns glossy screens into anti-glare filters, or protects a matte screen without making it glossy.
