Blake Borer very practical
Public bathrooms run out of soap. Campsites never had any. Somewhere between a long-haul flight and a trailhead toilet block, washing your hands properly becomes something you hope for rather than something you do. Fifty paper soap sheets in a case the size of a matchbook fixes that permanently.
Each sheet is a thin dissolving leaf of soap. Take one out with dry fingers, add water, and it breaks down into lather in a couple of seconds, then rinses away completely. Because they are dry, they cannot leak into a bag the way a bottle can, they are not a liquid for airport security purposes, and they weigh essentially nothing. The hinged case snaps shut so the remaining sheets stay dry.
Keep one in a daypack, one in the car and one in a handbag. They earn their place at festivals, on hiking trips, in campgrounds, at service station bathrooms and anywhere the dispenser is empty. Choose green, white or pink, or take the three-pack and spread them around. Designed for washing hands with water, so it is a soap rather than a waterless sanitiser gel.
