Lighten the load a little and take paper soap with you when you travel.
The little plastic case measures only 4.5cm x 6.5cm and contains 30 sheets of antibacterial soap. Simply remove a sheet from the pack, add water and lather away.
The paper soap pack doesn't contain liquid, so can be carried in hand luggage on flights and weighs very little.
Mint and eucalyptus fragrance.
