For years I have stored all my  ornaments in large cardboard boxes.  Now I have more boxes but they are smaller and much sturdier.  They are easier to carry and I can even stack them and they are easier to store not requiring such a large shelf space.  You can carry one with one hand and they are much safer.

Pros: The zippers close everything up securely, and the interior trays are very heavy duty so nothing is going to get smashed.
Cons: None.
