Life can be "overflowing" with small annoyances. The simplehuman bags (that you use with the corresponding trashcans) will NOT add to the list! Yes, they may cost a bit more, but they STAY PUT in the can until you choose to remove it! They do not collapse inward when you toss that large/round/ burnt pizza crust in all at once. Plastic is not conducive to a healthy planet, however with these bags I find I use less bags since they work so well with space management. Perhaps a biodegradable bag option might be in the future?
