A different garbage bag fits in every trash can. When purchasing, pay attention to the correct contents of the garbage bag and preferably choose a bag that matches the brand of your waste bin. Often there is a code attached to the trash that matches the code of the trash bag. That way you can be sure that you get one that suits your trash. Some trash bags have a handy zip closure so you can easily pull them out of the inner bin and put them out easily when the bag is full.
