US Mil Spec
Gov. Surplus.
This stuff is strong: you could tow a car with it.
Unused, 25' lengths.
I believe this is called "one inch": It's an inch wide when flat,
or when diameter is measured without stretching at all...
One picture shows it barely stretching to
swallow a "D" Battery.
The other shows it with 10 markers and could
hold a dozen if I had them...
Keep in mind about 25% of length is lost when
stuffed full.
