These Fish Eye 3D Eyes come in a 20-pack and are sized at 5/32" (4mm), designed to fit all standard vibrating blade baits like ours. Their stick-on design allows for quick and secure application. For enhanced durability, we recommend applying a drop of super glue—taking care to avoid the bait’s top surface to prevent clouding. These eyes add realistic detail to your lures, improving their effectiveness in attracting fish.
