Fuji Ultra Poly NOCP rod wrapping thread in Cobalt Blue #039 (Size A 100m spool)
Fuji Ultra Poly NOCP (No Color Preserver required) thread offers the same handling characteristics of the Ultra poly only it has been treated with color preserver.
Cobalt Blue is perfectly named. It reminds me of the brick streets in Old San Juan, PR. A bright blue that is somewhat tamed by a strong mineral element. Very nice!
