These 13-gallon bags fit in regular (smallish)-sized kitchen trash cans, and they're biodegradable, compostable, and even the package they come in is made from biodegradable, compostable, recycled materials with soy-based inks and dyes! Shit, what more do you want? And don't worry, they're shelf stable, and will not decompose until they are introduced to the earth's elements or micro-organisms in the soil. (But, we do recommend storing them in a dry, cool area and not putting a lot of wet trash in it.)
12 bags per box.
