Review on Pepperell 1 9Mm Parachute 100 Feet White by Tara Ford

I bought 4 different types of cord until I found this cord to match my existing cord in my channel is perfectly balanced. I used it to rebalance the channels for my tilt lock casement windows. Holds up well. Some of the other line I've bought that was the same gauge was much stiffer and didn't work well at blocking and grabbing or holding knots. It appears to have a single twisted central thread (core or core) with a woven outer covering (mantle). It stays tied well and goes well through the pulley system.
