Fishing bait moIds are used to produce DIY soft plastic baits. MoIds are made from heat resistant engineered stone. Plastisol (soft plastic) needs to be heated to 180 degrees Celsius (356 F) and injected into the moId using injector. When making baits you may add color pigments, attractants, glitters etc to achieve the desired look of the bait. Oil based greasing or cooking spray can be used to lubricate the moId prior to casting. Although it's not mandatory, it simplifies the bait extraction process and give a nice glossy look and needed scent to the baits. This product is only the bait moId itself. Additional materials like plastisol, coloring etc. needs to be purchased separately.The Z-Craw takes an elongated body with forward facing ribs and adds hook pockets top and bottom as well as fluttering claws, all in a streamlined package designed to slip into the heaviest cover with ease while also pulsating with the sound and fury of an angry crawfish
