I use these mainly as intended laundry bags for my bras. I also use one to collect dirty dish towels until I'm ready to wash them,usually once a week with a blanket or towels.In which I pour out the dish cloths into the washer,then throw in the bag too.They are fantastic for vacations to hold bras,underwear,and socks in so I'm not searching all over my bag for them,or accidentally dropping them on the floor around other people. Can be used to hold dirty clothes on a few day vacation where you won't have laundry access so everything is together and you know where it is,and that it's clearly dirty. They can be used to hold many other objects too like some bath toys. I like how they come in different sizes for the different needs of the days laundry. I usually do laundry once a week,but sometimes more often depending on what I need. So far they have held up well in the washer/dryer no signs yet of any tearing,or zipper issues,everything is a good as they arrived.
