The T Worm is a wacky rig style bait designed to be used on a jig head for smallmouth bass out of the river. I have been quite successful in my testing, the smallies really like to eat this one. See the video below:

The single cavity mold is designed to be used with the following injector: Amazon.com : Dimatteo Mold Injector 120 ml / 4 oz Aluminium Plastisol Soft Lures Molds : Sports & Outdoors
 
3D printed molds cannot verify if other injectors will or will not work with this mold. All sales are final.
