This Sunline Kyasutesuto Tapered Force is a specialized type of fly line, often called a 'yarn throw' or 'tenkara-style' line.

It's designed for simplicity and delicate presentations, especially in Japanese-inspired fixed-line fly fishing.

The line is tapered (not a level line), which means it's thicker at the butt end (about 26.4 ft / 8m) and gradually thins to a tippet section (about 3 ft?).

This taper helps transfer energy smoothly during your cast, allowing for quieter, more accurate fly placement.

It's 75 meters long (so you can cut it to your desired length), comes in a high-visibility yellow color, and is rated #5-12, which refers to its thickness/weight range.

It's known for being durable and having a special coating to reduce friction ('guided resistance') as it shoots through your rod's guides.

A great choice for anglers looking to experiment with tenkara, keiryu, or light-line European nymphing techniques where a traditional weighted fly line isn't desired.
