Pelican 1550 case. I live about a block from the ocean and noticed some pitting starting on an hatchet made out of 52100, and darkening on a chopper made out of A2. I bought the Pelican case and threw in some silica gel desiccant packs and everything has been all good. Here is a pic:
I figured there was too much unused space on the underside of the lid
. Side note, there are two glues that work on Pelican box plastic, one is made my 3M and is ~$30 a tube, the other is ShoeGoo ~$5 a tube.
