UV CHEWEE SKIN - Thin, super-stretchy, skin that DOES NOT have an adhesive backing. The UV coating falls into that 340 nanometer wavelength that fish can see up to 300-feet deep. So easy to work with. Use it for scud backs and wing cases; wind it on for worm, larvae or nymph bodies. UV-COLORS: (1)Black, (2)Glow-In-The-Dark, (3)Gray, (4)Blue, (5)Olive, (6)Orange, (7)Peach, (8)Pink, (9)Purple, (10)Red, (11)Rust, (12)Tan, (13)White, (14)Yellow, (15)Brown, (16)Caddis-Green, (17)Chartreuse, (18)Clear, (19)Cream
