I bought it after watching Douyin~~ I used it for a week, and it was so dirty~~ Fortunately, I bought two wisely at the beginning, one black and one white~~ But after all kinds of fancy tossing, I found that it is still thin and light~~ Even the film is good. Don't do it~~ It's been two years of streaking, and the screen without film is not spent! Then why should I spend money to buy some tempered film! !
