Read the following context and answer the question.
Context: Can you imagine if I had had to do this task with traditional Wite - Out instead of using the little miracle pictured above ? Somehow spreading out three thousand pages , waiting for them to dry ? Every single time I pressed the dispenser to the page , every time I heard little clicks of dispensing , I said Thank You to the good people at 3 M or whoever invented this object .
Question: What might be the advantage of the dispenser I 'm talking about ?
Answer:


The dispenser must not require drying out .
