I had found the ones I bought at the shops were made with Velcro that wasn't strong enough so they didn't last very long. I also wanted it to be a little larger so I could fit more poo bags in it. This works great, it fits about 6 bags scrunched up in it easily, I could probably fit 10 if I tried but six is enough. It's nice to have the bags Velcro stay closed and to know I have enough bags with me even if both dogs poop twice on a walk
