The Korda Kontour is a line with a diameter of 0.33mm. The package contains 200 meters of fluorocarbon line. A line that casts incredibly well, sinks like a brick and is very abrasion resistant. Kontour, as the name suggests, is very flexible compared to many other fluorocarbon lines and follows the contours of the lakebed. Other features are further casting distances and extreme accuracy. In short, an ideal fluorocarbon main line for fishing!
