I used one of the two sheets that were included. It was easy to apply, so I don't need the other one. If anyone is looking for one, please let me know. I've used one, so I'm listing it as "like new," but the remaining one is still in its package. Product Description: 【Two-Step Application & Automatic Dust Removal】 Simply cover and pull – it's a two-step process that makes application easy even for beginners. The film naturally adheres, using static electricity to draw dust from the screen, minimizing bubbles and ensuring a perfect application, significantly reducing application failures. NIMASO's latest automatic dust removal guide frame makes it easy for anyone to apply the film! You can easily apply the film without misalignment between the iPhone and the protective film. 【Blue Light Cut Function & Eye Fatigue Reduction】 With the blue light reflection technology certified by the US military "MIL-STD-810H" standard SGS (certification number: GZMR220702278001-1), blue light can be significantly reduced. This helps to alleviate eye fatigue and protect eyesight for those who spend long hours looking at their smartphone screen or playing games. (Please note: There may be slight differences in color compared to the images. Please understand.) Feature: Blue Light Cut
