.....and I went to my closet to check my Rolex boxes.

Low and behold, I found a thin layer of dust inside a few of them (haven't paid any attention to them for years).

Now my question is, do I have to send them to BSC (Boxes Service Center) or is there a way I can do this myself?

How do you service your boxes?
