I pour this into a cup each time, and I haven't put my mouth on it at all. I dried it naturally upside down. Please note that the plastic bottles are very soft and easily dented, so please be aware of any scratches during delivery. I will ship it in the original cardboard box. Since it is anonymous shipping, the price is a bit higher. How about for art projects, cat repellent, etc.? We also handle 2L x 6 bottles ◎ #NaturalWaterPets
