How to use
1: Hold the spout firmly and cut in the direction of the arrow. Please be careful not to hold the bag too tightly when cutting, as the contents may spill out. 2: Insert the spout into the opening of the container and slowly pour in the contents. Be careful not to press the bag too hard when pouring, as this may cause overflow. Always refill into an empty Steven Knoll Smooth Straight Treatment container. To prevent the introduction of bacteria, do not wash the container or pump before refilling. If you do wash them, dry them thoroughly. Refill the entire amount after using up the contents. Do not mix with water or other products. For hygienic use, we recommend replacing the bottle with a new one after refilling approximately three times. This is not a drink.
