This is an unlabeled tube of vintage American-made cotton yarn, so we don't have the exact details. It is on a straight brown plastic tube, rather than a cone. The yarn is matte in finish and a bit fuzzy, so it is not mercerized. We estimate the count as 30/2. It probably dates from the later part of the 20th century.

This tube weighs 10.7 ounces.  The estimated yardage is 2,000. The color is natural white.
