Twine brand says SecureLine. Spun cord, natural fiber, low quality, probably 35lbs limit or less, utility, probably use it in gardens, simple tasks or for arts and crafts.

550 is Parachute cord, military, named 550 because that's the weight it was tested at and supports.

Curiously Paracord actually has 6 different classifications, but the most commonly known is type 3 which is 7 inner strands. Although commercially avaliable cord usually isn't actually Paracord and far weaker, so don't trust what you buy at the crafts store or Walmart :P
