I bought these bags to replace a set of canvas reusable shopping bags I have been using for over 15 years. The canvas bags fold up small, and I stuff one of them with all the others and I'm ready to go. These new fabric totes have separate removable bottoms which give the bags shape and hold them open - but, the problem is, you either have to remove the bottom for storage, and then replace when you're ready to use in store, or figure out a way to carry them around with the bottoms already in place. Right now I'm hauling them around with bottoms in, stacked one inside the next, which makes a big bundle and lot of wasted space. Not loving this aspect of these bags. Also, the cashier at the store complained about the mesh bags I put my fruits and vegetables in, and took everything out because she couldn't read the tags through the dense white mesh. I have some other more see-through mesh bags and I will probably go back to using those because I have never gotten any complaints about them. Too bad, because otherwise these new mesh bags seem strong and well-made. I will have to use them for storage at home, I guess. Would not buy these again because of these problems, but will find ways to use them, since I took them out of the box and can't return.
