Dogipot Trash bags are made of sterner stuff than a typical trash bag. At 1.8 mil thick, these bags aren't prone to rip or tear easily. They are opaque black with a star-sealed bottom to maximize strength. These bags are environmentally friendly and break down long after service life without seeping toxins into the land using biodegradable plastic technology. Designed to be used in 30 to 35 gallon trash receptacles. Each box has 25 bags rolled inside and each order comes with two boxes.
