Everything about this product is good except the durability. The interior liner is torn (from the pressure of the steel spring closer?) after only two months use.
This works great for me since I keep it in my coat pocket and can easily reach my hand inside to get treats, and close the bag.
I carry doggy snacks and waste bags in mine. It's wonderful. Easy to open and close. I have a service dog and it hooks on her vest or I clip on my belt. I recommend this highly.
