Using the latest in photo-realistic holographic technology, Flymen has developed the most realistic range of 3D fish-eyes for fly tying on the planet at a very compelling price point. No longer will fly tiers have to rely on fish eyes created using an ”artist’s impression’’ of what they think fish eyes look like. There are twenty eyes per pack for the 3 mm (1/8″), 4mm (5/32″), 5mm (3/16″), 6mm (1/4″), 7mm (9/32″) packs. There are sixteen eyes per pack 8.5mm (11/32″), 10mm (3/8″) and twelve eyes per pack for the PREDATOR size 15mm (5/8″).
