When collectors use the term “white box” they are referring to a White Harbour Light box with the writing Castle Studios on it.

When collectors refer to the term “Brown Box” they are referring to a brown Box that the early Harbour lights were sent in. Most had Castle Studios written on them a, few didn’t.
If you have one without the Castle studios written on it. It would have to be certain dimensions and have a circular box stamp with California written on it.

To answer you question:
If you are selling two original Harbour light brown boxes that was used to ship one of the original H.L. in. Yes I would give you $40 dollars. laugh

If you are selling me plain boxes: NO I get mine from Office depot. eek
