You can use regular trash bags!
If a diaper pail can be "pretty" this one definitely is it! LOVE the fact that you can use normal, standard kitchen trash bags, which is not only convenient but saves money as well. No set-up. Easy to use. Definitely a little stinky when changing the bag, I think the metal absorbs a smell but as long as lid is closed you can't smell it. I do plan to get a munchkin baking soda puck to put in the bottom to see if that helps.
