Dual Use Shampoo / Shampoo packaging

We come into contact with one-packet shampoo often in life, which content is designed according to normal adults. However, one-packet shampoo cannot be used up after short-hair people and children open it, results in waste. Dual Use Shampoo is designed to provide two openings. When adults with short hair and children use it, they can open half of the shampoo in the polybag; normal adults can open the whole packet.
