These are really nice lingerie bags. They are soft but durable. They have a zipper closure and have a little strip of elastic to hide the zipper tab so it does not stick to your lingerie in the washer.
This is a set of 4 you get 1 small, 1 medium, and 2 large bags. I used one on a shirt with bead work, I turned the shirt inside out an this bag helped keep it that way and none of my beading was disturbed by thrashing around in the washer. These should stand up to several washings. I was given these bags in exchange for my honest review.
