Review on KOYO Flock Sheet with Enhanced Visible Light Absorption - 400mm x 950mm by Raquel Perkins

Small black fibers placed at the end are an economical way of capturing incident visible light, causing the flock to turn very black even in direct sunlight. I use it on my dashboard to improve driver and dash cam visibility when the sun is shining on the dashboard. When approaching a tunnel I can now see any vehicles that could be stopped in the darkness of the tunnel, which used to be an issue. And my dashcam no longer has a blurry image of the road in front of me.
