These bars of shampoo are the refills for the Natural Travel bar carrier.
This stuff is awesome! The shampoo is quality and lathers well. It can serve multiple functions Like shaving or even small laundering tasks like socks and undergarments . If purchased with the “Natural Traveler” case, it travels really well. This 3.5 oz bar of shampoo is is equivalent to 24 .oz of shampoo. You can use it in good conscience as the bar comes wrapped in paper and not a plastic bottle.
