I had a pepper spray with 30ml and wanted a smaller bottle. The 20ml- bottle is still quite large, to make them completely disappear in a woman's fist, but it should not also contain too little spray. I specifically searched for a pepper spray the brand Fox Labs, as this is supposed to be on the market one of the best. Previously had a mist spray, in which the goals easier, but the green dye erleichter certainly the objectives of this jet spray. If you wear the spray often directly in the hand, it is also advantageous that you have to push until the fuse aside before spraying. I think I chose the right product and am very satisfied!
