Block Jelly is a blend of opaque and jelly fibres. The opaque fibre has been designed to reflect fluorescence light from the tips and edges of the jelly fibre while creating a block colour in the water. Very importantly the fibres like its sister jelly fritz have been cut and compressed as small as technically possible. Very importantly this is an un-boosted fritz allowing it to flair open in the water while static and close fibres when pulled, giving the pattern lots of movement.
Mounted on a micro core and very forgiving to work with.
