The perfect material for tying Blobs, FABs and bright boobies. The FNF UV jelly has had a serious upgrade with a broader color range. The UV fiber has been blended with the new Jelly fiber creating a lovely fritz. The fibers are as narrow as is possible to allow them to flare in the water and create little UV balls of light. Some say the UV is best in dull conditions however my experience is the brighter the conditions the better the UV jelly works.
