JTS-111 - HICKORY WOOD SMOKE 2ozHICKORY WOOD SMOKE 2oz JT's MEGA STEAM Smoke FluidTM!!!! Thick, dense smoke output yet it dissipates quickly, leaving little or no train room fog hanging in the air. NON TOXIC. Comes in 2oz bottles with pin point end glass droppers for accurate filling. All of our smoke fluids are scented just right, not too heavy, not too light***. Petroleum based formula. Smoke itself is non toxic though I wouldnt suggest drinking it. Works great with most smoke
