This might be a puzzle to non-West Coast of North Americans. A Christmas tradition here is boxes of Japanese oranges which used to come in little wooden boxes, and now are in cardboard ones. The Chinese broke into this market a few years ago. This year the Chinese cardboard boxes are just coverings for a sturdy green plastic crate 18 cm x 25 cm by 12 cm deep ( 7 x 10 x 5 inches ). They will stack, and I think would be perfect for storing bulbs. Diane Whitehead Victoria B.C. Canada
