I just got my shipment of bulk 3D holographic eyes and they are awesome. Make sure to hit www.bustinbassbaits.com for holographic eyes. They sell the 3D ones, not the tape kind.
I ordered 500 for less than $10 with shipping through his Ebay store. Now I see he has a website that is even cheaper - $15 per 1000! My local fly shop sells 24 for $4 and for some reason I burn these things up. For my initial order I went with 4, 5 and 6mm silver and red eyes, but there are plenty other colors and sizes to choose from.
