This is 40 foot of foam cutting wire.
Its really .020 stainless aircraft saftey wire but works so good at cutting hat I have used it for 20 years. You could buy a lifetime supply elswhere at about about $15 per pound but they will not sell it in short lengths.
I know nichrome wire is finer and does a better job but it requires more power to heat and is much more expensive.
I preffer this wire over nicrome because it does the job and does not break as often. Much more forgiveing and afordable to first time users.
