The Trout / Finesse Worm is 3" long and .19" in diameter, tapering to .12".  This mold shoots super easy and makes perfect worms every time.  
Besides making a great Trout worm, it also makes a great smaller Bass bait: Wacky or Drop Shot.  Pan Fish love it also.  It is a super solid all around bait.
De-molding is as simple as just pulling them off the runner.
