I use these bags for just about everything while grocery shopping which is why I am back buying more and decided to leave this review. You can use for bulk mushrooms, loose potatoes, loose fruit, bulk nuts or anything else. Also much easier than cheese cloth for straining nut milks and it is easy to wash and re-use!
I stash this cotton bag in my purse and it's there when I need it! It keeps my produce clean while I shop and it is the size of a shopping bag so I just use it to carry my items out! I can put the bag directly into my fridge, too! I have not used it as a strainer.
