500FT Braided and Bonded, Black and White Mason Line refill is made of durable nylon. A braided variety wound on a 1" diameter core. #18 nylon has a tensile strength of 165lbs. Mixed coloured options are 'bonded' for extra durability. Bonding is a process that coats the string to make it more wear, UV and water resistant. The line is stiffer and easier to tie knots and the ends won't fray as much when cut.
