We are those hippie peeps that take canvas bags to the grocery store. We also take produce bags. We have purchased several kinds in the past but they each disappointed in one way or another. Not these! These bags are sturdy, come in great sizes, and have drawstring locks that actually, ya know, lock. A friend of mine has fruit fly issues during the summer sometimes and I'm going to gift her with a set of these - the mesh is fine enough to keep them out!
