This is a 1 inch (25mm) herringbone seatbelt style 100% polyester webbing, and is 1mm thick. This is sold by the yard (I will try to cut as continuous as I can).
Due to screen resolutions the colors may be slightly different in person. I provided a few pictures if different lighting to try to help give a more accurate idea of the color.
Retail orders normally ship out next business day, but can take up to a week. If ordered with preorder items it will all ship out when everything is in.
