GO Hefty 50
Style: White Pine Breeze, Size: 50 Count (Pack of 1)
They are best buy for the money. Scent is not overpowering like some are. Not cheap bags made strong and you can tell that when you start using them.

Great! Buy them!
Style: White Pine Breeze, Size: 50 Count (Pack of 1)
I learned that I only buy ultra strong! These are durable, I pack my garbage can full and these hold up! They smell good too. I also use them in my cat box (jump into the top kind) and that is one stinky situation, these hold up to the scooper and when it needs to be tossed it is still in one piece. (Cats dont have front claws)

TAKE THE TRASH OUT !
Style: White Pine Breeze, Size: 50 Count (Pack of 1)
I recently bought the Hefty Ultra Strong 30 Gallon Trash Bags and I am thoroughly impressed with their performance. These bags are perfect for handling heavy loads and tough trash, making them ideal for both household and industrial use. The 30-gallon size is perfect for larger trash cans, and the drawstring closure is incredibly convenient. It allows for easy tying and carrying, without worrying about the bag breaking or ripping. The drawstring also ensures that the bag stays securely in place in the trash can. The black color is great for concealing the contents, and the White Pine Breeze scent adds a pleasant touch that helps neutralize odors. The scent isn't overpowering but does a good job of keeping unpleasant smells at bay. These bags are truly break-resistant, leak-proof, and puncture-resistant. I've used them for a variety of tasks, from yard work to cleaning out the garage, and they have held up beautifully without tearing or leaking. The strength and durability of these bags are evident, even with heavy and sharp objects inside. Overall, the Hefty Ultra Strong Trash Bags are an excellent choice for anyone looking for reliable and durable trash bags. They offer great value for the price, and their performance has exceeded my expectations. Highly recommended for anyone needing a strong, dependable trash bag!
