The design on this bag is beautiful. It’s great that it locks, gives me peace of mind. It’s not as tho it is completely tamper proof but it still makes it difficult to get inside. It claims to be smell proof with the activated carbon. I wanted to test this out and the only way I could think of at the moment was to put a bunch of dog treats inside and let my extremely food driven dog try and find them. She acted like the bag didn’t even exist, so that’s a win in my book.
