These easy to use unbleached 100% cotton bags have no closures to fuss with, yet the flip over top provides a loose closure. Not water resistant, but great for dry items, instead of a throw-away bag. No plastic. Use to store produce, organize small items for travel or storage, keep one in the car or your bag with small toys, crayons, etc. Small approx. 5.5x6, medium 8.5x9 and large 11.5x12. Made in USA.
