I love these boxes! Meanwhile, I have determined on the 15 pieces at home - for storing Crafts, clothing, hats, books, toys, patterns, magazines, electrical cables, etc. The boxes are very stable and can withstand great stress, without tear at the corners or at the carrying straps. They also have a sturdy, thick zipper and see also still very nice. The size L fits of height and depth ideal in my cabinets.
