work, but as soon as you twist the hairpin, the paint is erased from the corners, in principle there is no point in buying black ones if you need to immediately after of the installation. I update and review all products I purchase 100% honestly. My reviews are real. I am real. I update every few months and again annually. It will also be featured on my YouTube and Instagram channels. I hope that this manufacturer or seller will contact me to resolve these issues as soon as possible.
