The 3" Skirted Chub Grub is a Twin Tail Grub with a Skirt. The bait can be injected one color, or you can inject the tail color, cut the grub off, and then inject the bait.
If you have one of our tube molds you do not need to buy a spline (the part that makes the tail) if you don't mind swapping out the tips - it can be used in both molds. If you do not already have one of our tube molds you will need the spline to make the tail. )
