Inexpensive and perfect for my needs
I wanted an inexpensive little bag into which I could easily empty my cat's uneaten wet food, twirl the top tightly so it could be hand-knotted closed, and deposit it into the kitchen trash until the next city trash pickup day.  It's strong enough not to rip during the process, apparently thick enough to blind any passing insect to its presence, and thin enough to knot.  I use it for bits of other food garbage as well.  Aside from feeling awful I'm using yet more plastic, I feel really great about having found these bags!
