Don't waste your money
I bought these for a cruise.  Used 4-5 sheets in a small sink full of water (it says you can use 1-2).  It did not clean our clothes.  Socks still smelled stinky after washing and hang drying.  It did not make any suds.  There are other laundry sheets out there that are better and just as easy to travel with.  Shampoo would have been better!
