You can tear it off after using it, or keep it. It will not affect the use whether you tear it off or not!The product has 3 fixing screws, which are used to fix the telescope. They can be put on the outside or inside of the telescope objective lens. It doesn’t matter which one is more convenient.When installing, it is sufficient to center it roughly. There is no need to emphasize that it must be completely centered. This has no effect on usage. The focus is operated through the focusing seat.It is not recommended to remove the film during the customer experience test. Once the film is removed, it will affect sales and no returns or exchanges are supported!When purchasing, it is recommended to consider the temporary placement of screws. For example, if the outer diameter of the telescope objective lens is 83mm, we recommend purchasing 80-110mm, and do not recommend 60-90mm. Because the M3 screw has a top size of about 6mm, it is generally necessary to choose a range size of more than 6mm.Fishbone plate*1 pieceScrews*3 pairsScrew anti-slip cover * 3 pieces
