Our ManSpray can be applied the same as other underarm deodorants you may have used prior. Our bottles use a Mist Sprayer that allows for a broadcast mist to your underarm for easy application to desired area. Just apply 3-4 sprays to clean, dry underarms and you'll be covered for the day.Please remember to shake well before use (the bottle, not yourself). Also, even though the ingredients are all natural we still recommend to keep it "External Use Only", please do not drink your ManSpray.
