Features

  • Strong string - This thick string is made of high quality nylon, which is stronger than polypropylene twine. The braided design allows this marking rope to hold up through the harshest conditions!
  • Braided, not twisted - Braided nylon mason line is superior to nylon twisted cord because twisted nylon twine will unravel after being cut. Braided mason line won't fray or unravel when tying knots.
  • Easy to use - Ideal for use with string line level or for any commercial twine heavy duty outdoor projects. Use as plumb line, or with surveyors plumb bob with string, or with a masonry line holder.
  • Garden string - This yellow string is perfect for use in the garden. Use it as tomato twine string to tie up tomato plants, or for wick watering african violets, or general landscaping twine.
  • Bright colors - Each braided masonry line roll is fluorescent and easy to see. Perfect outdoor string for use as landscape twine, property line markers, construction twine, or marker string.

    • It's twine. It works as expected.
Size: 250 Ft Roll Color: White
Nothing fancy here. It the right strength, thickness, weight, and a good quality for a twine. Works as you'd expect. Bought this to wrap up a folding Christmas 🎄 and it works great. Holds up outside when holding down over sized candy canes.

    • Strong, consistent, no fraying — exactly what it should be
Size: 250 Ft Roll Color: White
This twine does exactly what nylon string is supposed to do. It’s strong for the size, holds tension without stretching, and doesn’t fuzz or fray during use. The thickness is consistent along the length, which matters if you’re tying knots that need to stay put. Cuts cleanly, knots easily, and doesn’t slip once set. The bright white color is useful when visibility matters for gardening, bundling, or layout lines. The spool feeds smoothly without tangling or collapsing halfway through. Nothing fancy, no gimmicks, just reliable material that performs predictably. If you need dependable string rather than decorative twine, this is the correct choice. ... show more
