Best mason line
Best line like the dots in it so it’s easy to see depth. You will find it extremely hard to break it when it’s new.

Not the Best
I needed some in a hurry and got this brand. If you have the time to wait get the "W. Rose" brand. It has a lot less stretch and just has a more solid feel.

It's great!
In my opinion the best line for Masons. And it has a plastic center instead of cardboard so if it gets wet, it's not a mess. Fantastic line!
