I don't know Henan. I only know that OK8 has physical stores in Shenzhen Huaqiang North and Guangzhou, and others are agents. I bought it online, and it's easy to post it myself, because it's all electrostatic adsorption, but I can post it many times at a time. The most important thing is that it is a suit with several layers of protective film inside, which I can choose to paste. This is my favorite.
