It’s empty in here!
Being a dog trainer, I have tried pretty much every different treat bag there is. This is my favourite. It's lightweight, easy to attach and easy to access with the magnetic closure being exceptionally useful.
I bought this to carry full poo bags as having 3 dogs I needed some kind of holder as on a bad day I can end up with 3 or more full bags on a long walk. The top has a magnet close so easy to pop open drop in a full bag & close it, beats trying to carry multiple leads & full bags of poop!
