Hareline's Fluorescent Fly Eyes are the ultimate in bright fly tying and fishing lure eyes. These 3D domed stick-on eyes are extremely bright and fluoresce, making them very attractive to fish in dark murky water. Adhere them to your favorite baitfish patterns and fishing lures to add a pop of bright color. Fluorescent fly eyes feature an adhesive backing, but we recommend adding a drop of Zap-a-Gap for a permanent adhesion. Available in your choice of 4 popular colors in 8mm. 20 eyes per pack!
