Navy Blue PLA is a deep, dark blue filament. Use it for team and school colors, ship and naval models, and uniform and cosplay props. Want a brighter blue? See Cobalt Blue. Like all COEX 3D Standard PLA, it's made in our Green Bay, Wisconsin facility from virgin NatureWorks Ingeo 4043D resin (colorant only, no fillers) and held to ±0.03mm

N-Blue
Navy Blue PLA was great. Coex3D is my sole source for print filament. The blue worked smoothly and uniformly. To suggestions: (1) My wife would like to see "Sage Green". (2) Put the logo/color label on both sides of the PLA reel. Blank side is all that shows when mounted on my printer and would be convenient to easily see the color name without walking up to the printer.
