Clever marketing idea

Take five products, they pack in miniature vessels, give you a plastic bag to - ready is the Nivea-travel set.
I have to admit, so clever, no one has so far implemented this insane flight safety line in a product.
And it works: My daughter loved the set for hand luggage.
Personally, I find the small pack sizes converted far too expensive, but because you have probably weigh practicality to profitability.
The set includes: Nivea Sun Nourishing Sun Milk SPF30, Nivea Volume Sensation Care Shampoo, Nivea Creme Care, Nivea Care Intensive Care nd the Nivea anti-perspirant Deodorant Dry Comfort.
The products are Nivea typical class, but I would be set too expensive.
