I just went on a holiday (within Australia of course). Using the different size bags to pack various toiletries was super handy. I also have more than one large bag which is the best size for cloth nappies when you change baby in the bedroom and your dry pale is in the laundry.
These are great wet bags, they feel nice and sturdy and the size is brilliant.
I'm not super delighted that they only come in the 3 pack now, but the large and medium are both brilliant sizes, so I'm happy to find a use for the small!
