I have been using these storage boxes for a long time and find them vbery easy to assemble and they are sturdy enough to stack them and not have them collapse or get weak at all. They are vbery good to use for storage of craft projects that I have started and wish to complete some day in the future. Now that I am 80 years old I think I had better get on the ball so as not to leave too many half completed projects that my children will find and wonder - WHY IN THE WORLD DID SHE START THIS PROJECT AND NOT FINISH IT AT ALL.
This is my favorite box for moving; it is affordable reusable a managable size stacks well and looks uniform for storage/organizing. It is almost impossible to overload it making it easy for senior citizens to organize themselves without having to depend on others. I like being able to move items & leave them in their boxes for organizing and storage. Space for labeling is well placed and large enough to allow ample notes for objects within the box.
