I ordered more sets of these ornament organizers this year.  I was determined to get rid of the ratty cardboard boxes I have used for years and carried with me throughout life.  There had to be a better way to store my ornaments.  HINT: Use foam core board cut to size only on the bottom of the bin for extra support.  The cardboard supplied is tricky to assemble and can be folded or just use less pieces of the cardboard to make the openings larger for storage of larger ornaments and accessories.  I bought other containers which match these and the bins can hold a lot of pieces!
