Special Design: other sellers use screws on both sides to fix the protective shell on the laser module, and the screws on both sides of our protective shell are used to adjust the arc, which can make it more convenient for you to adjust the arc and better protect your Eye. The bending angle of our protective shell is used to better fix it on the Laser module, so when you receive the protective shell, you will find that the protective shell is curved, because its role is to fix it on the Laser module more firmly.
