This matchbox-sized plastic pack holds 50 paper-thin sheets of travel laundry soap. The dry soap won't leak into luggage and is easy to portion out conservatively – a sheet or two is all you need for a load of laundry. It's also completely biodegradable. Each pack is only 2 3/4" × 1 3/4" × 3/4" overall, so they're easy to carry. TSA approved for air travel. Can be used with our Scrubba wash bag.
