My laundry bag set is great for washing my under garments separate. It does help to last longer. Each zipper is tuckable inside tiny strap for staying closed during wash. Sometimes things with clasps get caught in my machines. This will prevent from happening. Also each bag is a different size for handling small or larger quantity.  Also reusable over and over. Hang up to dry when finished and grab the next load for use. I was given the opportunity to get this item at a DISCOUNT for my personal unbiased honest review of my testing experiences also not in a relationship with seller to form this honest opinion of their products.
