A twine is slightly thicker than a thread and is used in many different purposes ranging from household to construction. The Yellow Neon Twine from Tru-Guard is a heavy-duty twine which is commonly used by masons for making landscaping layouts and for staking construction sites for bricks and concrete. Made from nylon strings, this twine has a lot of strength and can hold heavier items as well without breaking. The elasticity of the twine allows it to stretch in order to withstand the pressure and then come back to its original shape.
