I (2 pieces) bought the bag in order not always throw away the slippery soap residue. A filled purse I use in the garden, the other in the utility room. The plastic fabric cleans SUPER my always absolutely filthy finger gardening and chimney cleaning, because I never use gloves. Great side effect! Simply with the plastic a little scrub - clean! With regard to the closure I do with the rubber bands a noose around the bag opening and pull it down tightly. The bag hanging on taps and are always tied firmly.
