Fluoro Brite is versatile in that it can be used as a tying thread or, untwisted, as a floss. The fluorescent color glows under a UV light. All colors flouresce in the water from one hour before sunrise through one hour after sunset. (Even though not visible to human eyes, UV rays from the sun during those hours are being refracted through our atmosphere, causing flies' hot spots to glow.) Fluor Bright size is 120 denier and 6/0 diameter. Recommended hook size #10-#2/0. (Use split thread down to #20.) 25m (27 yds) per spool.
