All 15 colors of our Metallic thread conveniently boxed. Superior metallic thread which is colorfast, withstands fading from UV light and harsh laundering. Has a polyester core wrapped in rice paper that prevents “kinking” as thread unwinds from the spool. Runs smoothly through thread pre-tensioners which means fewer thread breaks. Boxed set of all 15 colors on 1000 meter spools.
