This is the "large" size about 8 5/8" (218 mm)
The material is a high strength dacron/nylon mix used by sailmakers to make leech tensioning lines.
And the "larger" size about 10" (254 mm). As you can see they all are about the same (colored beads are different on each) Size is controlled by how many bights are made in the grommet and can vary from just a few to a huge number. Think napkin ring all the way up to hatband size.
