Features 5

  • 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 orange 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.

Strong and vibrant
Size: 500 Ft Roll Color: Flo Yellow
I needed this to be bright and easy to see, and also high quality enough not to sag over time after being tied tightly between two posts. It did the job great, much better than other string/twine I’ve used. Good value for the price, there’s a lot there.

It comes as described
Size: 250 Ft Roll Color: White
It is very strong and easy to use. I purchased it to replace all the old strings on my wind chimes. The thickness of the string was exact as shown. Great value for the money.

Great Find!
Size: 250 Ft Roll Color: Flo Pink
Exactly what I was looking for. The string is good quality and strong. I'm looking forward to using it in my garden.

Sturdy
Size: 1000 Ft Roll Color: White
The twine is quite a bit thinner than I would have liked, however it will do. Seems very sturdy. Used it outside to mark property line and hopefully will last a long time. Unrolled very easy with no mess.
