I specifically did a search for waterproof bags on Amazon and this came up.  I purchased this for the purpose of storing toiletries in our suitcases for a flight to Florida.  I wrapped plastic bottles with liquid in ziploc bags and put them inside the large tote.  Well, one of the bottles containing Witch Hazel leaked out of the ziploc and went RIGHT THROUGH this tote to the inside of the suitcase.  I'm glad it was just Witch Hazel and caused no damage.  After that I put the Witch Hazel inside 2 ziplocs and it made it through the return trip without spilling out into the rest of the suitcase.  I am upset that these totes were marketed as WATERPROOF when they ARE NOT!!  These bags are not suitable for the purpose that I bought them, but I can use them as totes for other things.  There are a nice large size.
