Hyper Tough 18 mason's white line is a twisted rope used to create straight lines and a level surface. It is a heavy duty, mid-stretch string that is perfect for a wide range of indoor and outdoor activities, including fishing, boating, masonry, crafting, gardening, marking and DIY projects. A mason's line is necessary when doing these projects because you will not have to pick up the level so many times.

The other great aspect of this twine is it will not sag like ordinary twine tends to do.
Polypropylene fibers provide a durable, long-lasting line that is naturally resistant to moisture, chemicals, oils, rot and weather conditions.
Never use this product to secure large flat surfaces or objects.
