Why Need to Buy This Item Removing the display requires cutting through the adhesive around the perimeter of the screen. After the adhesive is cut, it cannot be used to re-seal the display in place, so you'll need to apply a new set of adhesive strips. Adhesive strips must be replaced every time after the display is removed for repair or upgrade purposes, these are the highest quality adhesive stickers available but they require 100% correct installation upon perfectly clean parts that have no trace of dirt/ dust or the previous adhesive tapes for maximum contact heat the adhesive with hair dryer before applying. Please note that these adhesive stickers are designed for A1418 and will NOT work for A1419 as there are larger stickers designed specifically for that model.
