Polar Fibre is a very fine and soft synthetic fibre, which is fixed on a fine mat. You can easily cut the exact amount of Polar Fibre you want from the mat. Each fiber tapers towards the tip, just like a natural hair. So you simply cut a tuft from the mat and it will automatically have a fishy, tapered shape that tapers towards the end, without the need to snip it around. This makes tying very easy.
