I take my Naturel shampoo and conditioner bars along with me on my long International trips, because I love the product and also because I hate adding any more plastic waste to the planet with the tiny sample size plastic bottles that are supplied in every hotel worldwide. Previously, I carried them in their original cardboard boxes, which got a bit messy. These small tins are the perfect size and so light weight that they don't add any bulk to my travel kit, and my shampoo / conditioner bars stay dry and unmarred.
