The blue-formula Antari FLL-10 Low Fog Effects Fluid, in 2.6 gallons, is specifically developed for low fog effects. The FLL fluid can produce a thicker low fog that dissipates in air fast without creating too much unwanted rising fog. Additionally, this fluid is an odorless, non-irritating, non-toxic, and non-flammable water-based composition that leaves no oily residue. All the ingredients are FDA approved.
