I received the sealing strip. The quality is very good, and installation is simple and convenient. Friends who need it can refer to this when buying. Personally, I find it quite good and have a positive review!
Installation was very easy; after installation, the door seals worked very well, effectively improving sound insulation with minimal noise. They are airtight, so there isn't much dust inside the car, keeping it cleaner and saving a lot of cleaning time. Overall, I am extremely satisfied.
