The Baby Bare mini wet bags are a generous size, bigger than mini wet bags from lots of other brands. The zip also opens across the long edge (the side) instead of the short edge (the top) of the bag, so it is wider and roomier to get a dirty poopy nappy in there! You don't have to squish up the nappy to fit it in! It is even a good size to be used as a purse with your phone and keys in it too. And great price. These are my favourite mini wet bags for sending to childcare for the dirty nappies.
