These Dog Poop Bags make it convenient to clean up after our dog.The product description page says these bags are ".......Leak-proof & Extra Thick & Durable....."First, these bags feel thin. I held a bag with two fingers of both hands, and gently stretched it. The bag immediately started showing white area (note that the bags are green color) at the point where the bag started to stretch (see pic that I labeled "white area").Second, I agree that the bags are leak-proof, as we've picked up solid,as well as somewhat liquid, dog poop, and the bags have not yet leaked. The bottom of the bags hold well despite the weight of the poop.I like how easy it is to separate one bag from the rest of the roll.The pattern name is lavender incense.I sniffed the bags, but could not smell a scent.These bags do not have handles.Overall, these Niumanery dog bags are useful to dispose pet poop in.These are perfect. They are large enough for my shepherd mix. They don't leak or break and, once knotted, odors are minimized and I can carry them to a garbage pail without holding my nose. And, they are biodegradable. Recommended.Having extra rolls of waste bags for my dogs is always a good thing. I found these bags to be quite sturdy, well sized and easy to separate when needed. Now that we have three dogs in the house, it never hurts to have a good stock pile of waste bags.I really like how well it is designed. The quality of it is very strong as well. I would get this again once I use it allFit's perfectly in the dogs bag holder. The wife loves them and uses them daily without issue.
