It's a simple, pre-rigged, scented platic worm made by this a little company in Ft. Wayne Indianna. You can get them in a few tackle shops up in Canada (Grimby Tackle for one) but the best colours sell out very quickly. I can't explain why, but this platic worm outperforms any other I have even seen or heard of. It falls better, crwals better, smells better, etc. And although the company promotes them for for bass, I have found that any fish that would ever contemplate biting a real worm will bite this one.
