Stroft FC2 Fluorocarbon tippet

Diameter: 0.09 mm – 1.10 mm 
Tensile Strength: 1.00 kg – 62.00 kg 
Length: 10 m – 1000 m 
Color: Crystal transparent

Similar to FC1 – but with slightly reduced knot strength. 
Significantly more cost-effective than FC1 and thus especially suitable for all types of fishing where the special properties of fluorocarbon are also desired in the main line. 
(Also available in the diameters 0.72 mm, 0.82 mm, 0.90 mm, and 1.10 mm). The STROFT FC2 has a similarly high linear tensile strength as STROFT FC1. 
However, the knot strength is slightly less. Besides being used as a more affordable leader material, 
STROFT FC2 is therefore ideally suited when the main line's importance is placed on abrasion resistance, sinking behavior, sensitivity, feedback, hook-setting stretch, lifespan, and visibility/invisibility.

Note: The term "Fluorocarbon" is commonly used in fishing to describe a type of fishing line.
