Step 2: If the nozzle is small, it will not fall easily. Generally, packages with individual bottles will be given a funnel, which can be used to pour slowly.
Step 3: Cosmetics should also be classified and put in separate bottles. For example, toner or spray is recommended to be poured into spray subcontracting and bottling, make-up water or essence is recommended to be poured into wide-mouth subcontracting and bottling, shower gel and emulsion are recommended to be poured into duckbill pressure bottles, and cream and makeup remover are recommended to be poured into cream round bottles. Generally, there is a small spoon in the sub-bottle of cream, which can shovel the cream into the sub-bottle bit by bit.
Step 4: If you can't tell what to pour, you will often buy a set of bottles marked with oil.
