These are great little draw-string bags that we use in the mio nappy bin. They fit perfectly and hook into the top of the bin so that they don't slump down as nappies go in. Just un-hook and put in the washing machine with the nappies! No need to get dirty hands or have to route around looking for the top of the bag. They are good quality and wash well, holding their shape and don't shrink. Would definitely recommend these.
