Very convenient size for walking and good quality construction. 1 star was removed because the clip that attaches to the belt breaks easily. However, you can pass the bag through the loop. For its price, though, it is a very good choice.

No matter what I put inside (croquettes, hard and soft treats, etc.), it "leaks" from the bag, so I honestly don't understand what type of treats it is intended for.

From this perspective, compared to a classic food bag, the only advantage is the hook that attaches to the belt/clothes, etc.

I washed it, put a food bag inside so that nothing leaks or gets oily.

Very convenient and good size for croquettes at least. For cookies sized 3-4cm it is small, it doesn't fit many. The little loop that goes through the belt or strap of the banana (waist bag) is very helpful. The closure broke very quickly. Also, for oily croquettes it is not the best, it needs frequent washing because it releases oil externally
